Luminescence device and display apparatus
Abstract
In a luminescence device formed of one or plural layers of
organic film between a cathode and an anode, at least one layer is
a luminescence layer, and a luminescence molecule of a metal
coordination compound having a basic structure represented by
formula (1) ML.sub.mL'.sub.n and having a substituent on at least
one of cyclic groups incorporated as a guest in a host material at
a concentration of at least 8 wt. %, which is higher than a
concentration at which a luminescence molecule of a similar
structure but having no substituent exhibits a maximum luminescence
efficiency to form the luminescence layer. As a result, a
high-efficiency luminescence device is provided, which is less
liable to cause concentration extinction even when a luminescence
molecule is contained at a high concentration relative to the host
material in the luminescence layer.

BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] The present invention relates to an organic film
luminescence device for use in a planar light source, a planar
display, etc.
[0004] The present invention relates to a luminescence device using
an organic compound, more particularly to a high-efficiency
luminescence device containing in its luminescence layer a
luminescence material comprising a metal coordination compound less
liable to cause concentration extinction even when used at a high
concentration.
[0005] 2. Background Art
[0006] An old example of organic luminescence device is, e.g., one
using luminescence of a vacuum-deposited anthracene film (Thin
Solid Films, 94 (1982) 171). In recent years, however, in view of
the advantages, such as easiness of providing a large-area device
compared with an inorganic luminescence device and a possibility of
obtaining desired luminescence colors in view of the development of
various new materials and drivability at low voltages, an extensive
study related to forming a luminescence device of a high-speed
responsiveness and a high efficiency has been conducted.
[0007] As described in detail in, e.g., Macromol. Symp. 125, 1-48
(1997), an organic EL device generally has a structure comprising
upper and lower electrodes and a plurality of organic film layers
between the electrodes formed on a transparent substrate. Basic
structures thereof are shown in FIGS. 1(a) and (b).
[0008] As shown in FIG. 1, an organic EL device generally has a
structure comprising a transparent electrode 14, a metal electrode
11, and a plurality of organic film layers therebetween on a
transparent substrate 15.
[0009] In the device of FIG. 1(a), the organic layers comprise a
luminescence layer 12 and a hole-transporting layer 13. For the
transparent electrode 14, ITO, etc., having a large work function
are used, for providing a good hole-injection characteristic from
the transparent electrode 14 to the hole-transporting layer 13. For
the metal electrode 11, a metal, such as aluminum, magnesium or an
alloy of these, having a small work function is used for providing
a good electron-injection characteristic. These electrodes have a
thickness of 50-200 nm.
[0010] For the luminescence layer 12, aluminum quinolynol complexes
(a representative example thereof is Alq3 shown hereinafter), etc.,
having an electron-transporting characteristic and luminescence
characteristic are used. For the hole-transporting layer,
biphenyldiamine derivatives (a representative example thereof is
.alpha.-NPD shown hereinafter), etc., having an electron-donative
characteristic are used.
[0011] The above-structured device has a rectifying characteristic,
and when an electric field is applied between the metal electrode
11 as a cathode and the transparent electrode 14 as an anode,
electrons are injected from the metal electrode 11 into the
luminescence layer 12 and holes are injected from the transparent
electrode 15. The injected holes and electrons are recombined
within the luminescence layer 12 to form excitons and cause
luminescence. At this time, the hole-transporting layer 13
functions as an electron-blocking layer to increase the
recombination efficiency at a boundary between the luminescence
layer 12 and hole-transporting layer 13, thereby increasing the
luminescence efficiency.
[0012] Further, in the structure of FIG. 1(b), an
electron-transporting layer 16 is disposed between the metal
electrode 11 and the luminescence layer 12. By separating the
luminescence and the electron and hole-transportation to provide a
more effective carrier blocking structure, effective luminescence
can be performed. For the electron-transporting layer 16, an
electron-transporting material, such as an oxadiazole derivative,
is used.
[0013] Known luminescence processes used heretofore in organic EL
devices include utilizing an excited singlet state and utilizing an
excited triplet state, and the transition from the former state to
the ground state is called "fluorescence" and the transition from
the latter state to the ground state is called "phosphorescence".
And the substances in these excited states are called a singlet
exciton and a triplet exciton, respectively.
[0014] In most of the organic luminescence devices studied
heretofore, fluorescence caused by the transition from the excited
singlet state to the ground state has been utilized. On the other
hand, in recent years, devices utilizing phosphorescence via
triplet excitons have been studied.
[0015] Representative published literature may include:
[0016] Article 1: Improved energy transfer in electrophosphorescent
device (D. F. O'Brien, et al., Applied Physics Letters, Vol. 74,
No. 3, p. 422 (1999)); and
[0017] Article 2: Very high-efficiency green organic light-emitting
devices based on electrophosphorescence (M. A. Baldo, et al.,
Applied Physics Letters, Vol. 75, No. 1, p. 4 (1999)).
[0018] In these articles, a structure including 4 organic layers
devices as shown in FIG. 1(c) has been principally used, including,
from the anode side, a hole-transporting layer 13, a luminescence
layer 12, an exciton diffusion-prevention layer 17 and an
electron-transporting layer 11. Materials used therein include
carrier-transporting materials and phosphorescent materials, of
which the names and structures are shown below together with their
abbreviations.
[0019] Alq3: aluminum quinolinol complex
[0020] .alpha.-NPD:
N4,N4'-di-naphthalene-1-yl-N4,N4'-diphenyl-biphenyl-4'4-diamine
[0021] CBP: 2,9-dimethyl.-4,7-dipheny 1,-1,10-phenanthroline
[0022] PtOEP: platinum-octaethylporphyrin complex
[0023] -Ir(ppy).sub.3: iridium-phenylpyridine complex. ##STR1##
[0024] The above-mentioned Articles 1 and 2 both have reported
structures as exhibiting a high efficiency, including a
hole-transporting layer 13 comprising .alpha.-NPD, an
electron-transporting layer 16 comprising Alq3, an exciton
diffusion-preventing layer 17 comprising BCP, and a luminescence
layer 12 comprising CBP as a host and ca. 6% of
platinum-octaethylporphyrin complex (PtOEP) or
iridium-phenylpyridine complex (Ir(ppy).sub.3) as a phosphorescent
material dispersed in mixture therein.
[0025] Such a phosphorescent material is particularly noted at
present because it is expected to provide a high luminescence
efficiency in principle for the following reasons. More
specifically, excitons formed by a carrier recombination comprise
singlet excitons and triplet excitons in a probability ratio of
1:3. Conventional organic EL devices have utilized fluorescence of
which the luminescence efficiency is limited to at most 25%. On the
other hand if phosphorescence generated from triplet excitons is
utilized, an efficiency of at least three times is expected, and
even an efficiency of 100%, i.e., four times, can be expected in
principle, if a transition owing to the intersystem crossing from a
singlet state having a higher energy to a triplet state is taken
into account.
[0026] However, like a fluorescent-type device, such an organic
luminescence device utilizing phosphorescence is generally required
to be further improved regarding the deterioration of luminescence
efficiency and device stability.
[0027] The reason for the deterioration has not been fully
clarified, but the present inventors consider it to be as follows
based on the mechanism of phosphorescence.
[0028] In the case where the luminescence layer comprises a host
material having a carrier-transporting function and a
phosphorescent guest material, a process of phosphorescence via
triplet excitons may include unit processes as follows:
[0029] 1. transportation of electrons and holes within a
luminescence layer,
[0030] 2. formation of host excitons,
[0031] 3. excitation energy transfer between host molecules,
[0032] 4. excitation energy transfer from the host to the
guest,
[0033] 5. formation of guest triplet excitons, and
[0034] 6. transition of the guest triplet excitons to the ground
state and phosphorescence.
[0035] Desirable energy transfer in each unit process and
luminescence are caused in competition with various energy
deactivation processes.
[0036] Particularly, in a phosphorescent material, this may be
attributable to a life of the triplet excitons, which is longer by
three or more digits than the life of a singlet exciton. More
specifically, because it is held in a high-energy excited state for
a longer period, it is liable to react with surrounding materials
and cause polymer formation among the excitons, thus incurring a
higher probability of a deactivation process resulting in a
material change or life deterioration, as we have considered.
[0037] Needless to say, a luminescence efficiency of an organic
luminescence device is increased by increasing the luminescence
quantum yield of a luminescence center material, but it is also an
important factor for enhancing the luminescence intensity of the
device to increase the concentration of a luminescence material in
the luminescence layer.
[0038] The luminescence intensity is increased in proportion to the
concentration of a luminescence material in a luminescence layer in
the case of a low concentration (up to several wt. %) of the
luminescence material in the luminescence layer. However, above
several % or 7%, a deviation from the proportional relationship is
observed, and the luminescence intensity is rather lowered to
result in a worse efficiency. This phenomenon is reported in
Japanese Laid-Open Patent Application (JP-A) 05-078655, JP-A
05-320633, etc., and is known as concentration extinction or
concentration deactivation.
[0039] Actually, in the case of using Ir(ppy).sub.3 in CBP as the
host material, the best luminescence efficiency is attained at a
concentration of ca. 6-7%, and the luminescence efficiency is
rather lowered thereabove, down to about a half at 12%
concentration and 1/10 or below at 100% concentration (Applied
Physics Letters 4, vol. 75, 1999).
[0040] The phenomenon is caused by abundant presence of molecules
in the triplet excited state waiting for luminescence in the case
of a phosphorescence substance having a life of triplet exciton
longer by 3 digits or more than the life of the singlet exciton. In
this state, thermal deactivation of losing energy due to a mutual
interaction of triplet excitons is liable to occur. This is called
triplet-triplet extinction and is associated with a lowering in
luminescence efficiency at a high current density. Further, it is
also considered that due to a long retention time at a high energy
state, the excitons have an increased probability of reacting with
a surrounding material and forming polymers of excitons, thereby
causing deactivation, or even leading to a material change or a
deterioration of useful life.
DISCLOSURE OF INVENTION
[0041] An object of the present invention is to provide an organic
luminescence device of a higher luminescence intensity by
suppressing the above-mentioned concentration extinction phenomenon
and providing an environment of using a luminescence material at a
higher concentration.
[0042] More specifically, an object of the present invention is to
provide a luminescence material less liable to lead to
concentration extinction even when used at a high concentration
with respect to the host material in a luminescence layer by
introducing a substituent group into a metal coordination compound
as such a luminescence material.
[0043] A more specific object of the present invention is to

phosphorescent second organic compound represented by formula (1')
shown below, and the second organic compound is present at a

and L' are mutually different bidentate ligands; m is 1, 2 or 3; n
is 0, 1 or 2 with the proviso that m+n is 2 or 3; a partial
structure ML.sub.m is represented by formula (2) shown below and a
partial structure ML'.sub.n is represented by formula (3), (4) or
(5) shown below: ##STR2## wherein N and C are nitrogen and carbon
atoms, respectively; A and A' are respectively a cyclic group
capable of having a substituent and bonded to the metal atom M via
the carbon atom; B, B' and B'' are respectively a cyclic group
represented by a formula of (6)-(14) shown below capable of having
a substituent and connected to the metal atom M via the nitrogen
atom: ##STR3##
[0044] According to another aspect, the organic luminescence device
of the present invention is a luminescence device comprising at
least one layer of organic film disposed between a cathode and an
anode and including at least one luminescence layer, that is
characterized by containing a luminescence molecule of the formula
(1) having a substituent and showing a maximum luminescence
characteristic at a concentration higher than a concentration at
which a luminescence molecule of a similar structure but having no
substituent shows a maximum luminescence efficiency.
[0045] More specifically, in a luminescence device comprising at
least one organic film layer between a cathode and an anode,
including at least one luminescence layer, it is preferred that a
luminescence molecule of the formula (1) including at least one
cyclic group having a substituent is contained at a concentration
higher than a concentration at which a luminescence molecule of a
similar structure shows a maximum luminescence efficiency.

BEST MODE FOR PRACTICING THE INVENTION
[0052] Basic device structures according to the present invention
are similar to those shown in FIGS. 1(a), (b) and (c).
[0053] More specifically, as shown in FIG. 1, an organic
luminescence device generally comprises, on a transparent electrode
15, a 50 to 200 nm-thick transparent electrode 14, a plurality of
organic film layers and a 10 to 500 nm-thick metal electrode 11
formed so as to sandwich the organic layers.
[0054] FIG. 1(a) shows an embodiment wherein the organic
luminescence device comprises a luminescence layer 12 and a
hole-transporting layer 13. The transparent electrode 14 may
comprise ITO, etc., having a large work function so as to
facilitate hole injection from the transparent electrode 14 to the
hole-transporting layer 13. The metal electrode 11 comprises a
metal material having a small work function, such as aluminum,
magnesium or alloys of these elements, so as to facilitate electron
injection into the organic luminescence device.
[0055] The luminescence layer 12 comprises a compound according to
the present invention. The hole-transporting layer 13 may comprise,
e.g., a triphenyldiamine derivative, as represented by .alpha.-NPD
mentioned above, and also a material having an electron-donative
property as desired.
[0056] A device organized above exhibits a current-rectifying
characteristic, and when an electric field is applied between the
metal electrode 11 as a cathode and the transparent electrode 14 as
an anode, electrons are injected from the metal electrode 11 into
the luminescence layer 12, and holes are injected from the
transparent electrode 15. The injected holes and electrons are
recombined in the luminescence layer 12 to form excitons, which
cause luminescence. In this instance, the hole-transporting layer
13 functions as an electron-blocking layer to increase the
recombination efficiency at the boundary between the luminescence
layer 12 and the hole-transporting layer 13, thereby providing an
enhanced luminescence efficiency.
[0057] Further, in the structure of FIG. 1(b), an
electron-transporting layer 16 is disposed between the metal
electrode 11 and the luminescence layer 12 in FIG. 1(a). As a
result, the luminescence function is separated from the functions
of electron transportation and hole transportation to provide a
structure exhibiting more effective carrier blocking, thus
increasing the luminescence efficiency. The electron-transporting
layer 16 may comprise, e.g., an oxadiazole derivative.
[0058] FIG. 1(c) shows another desirable form of a four-layer
structure, including a hole-transporting layer 13, a luminescence
layer 12, an exciton diffusion prevention layer 17 and an
electron-transporting layer 16, successively from the side of the
transparent electrode 14 as an anode.
[0059] Each of the organic film layers 12, 13, 16 and 17 is formed
in a thickness of at most 200 nm, and particularly the luminescence
layer 12 is formed in a thickness of 5-200 nm.
[0060] The present inventors have discovered that the use of a
metal coordination compound including a substituted cyclic group
and represented by the above-mentioned formula (1) results in a
high efficiency luminescence and a lesser likelihood of
concentration extinction even at a high concentration than the
conventional level due to suppression of an inter-molecular
interaction.
[0061] It has been also found that the suppression of concentration
extinction is an effect attributable to a substituent on the metal
coordination compound, and the concentration extinction becomes
less liable to occur not regardless of the coordination number of
ligands but owing to the presence of a substituent on at least one
ligand.
[0062] Particularly, as a result, in a conventional
phosphorescence-type organic EL device, the luminescence material
can be used at a high concentration of 8% or higher in the
luminescence layer, thereby providing an organic EL device
exhibiting a high luminescence luminance.
[0063] The metal coordination compound used in the present
invention emits phosphorescence, and its lowest excited state is
believed to be an MLCT* (metal-to-ligand charge transfer) excited
state or .pi.-.pi.* excited state in a triplet state, and
phosphorescence is caused at the time of transition from such a
state to the ground state.
[0064] It is generally said that phosphorescence life is shorter at
MLCT* than at .pi.-.pi.*, but the molecular structure suppressing
the concentration extinction used in the present invention is
effective for both MLCT* and .pi.-.pi.* as the lowest excited
state, and the molecule can be doped at a high concentration in the
luminescence layer in either case.
[0065] The luminescence material of the present invention exhibited
a high phosphorescence yield of from 0.1 to 0.9 and a short
phosphorescence life of 0.1--30 .mu.sec. The phosphorescence yield
referred to herein is a relative quantum yield, i.e., a ratio of an
objective sample's quantum yield D(sample) to a standard sample's
quantum yield .PHI.(st) and is determined according to the
following formula:
.PHI.(sample)/.PHI.(st)=[Sem(sample)/Iabs(sample)]/[Sem(st)/Iabs(st)],
wherein Iabs(st) denotes an absorption coefficient at an excitation
wavelength of the standard sample; Sem(st), a luminescence spectral
areal intensity when excited at the same wavelength: Iabs(sample),
an absorption coefficient at an excitation wavelength of an
objective compound; and Sem(sample), a luminescence spectral areal
intensity when excited at the same wavelength.
[0066] Phosphorescence yield values described herein are relative
values with respect to a phosphorescence yield .PHI.=1 of
Ir(ppy).sub.3 as a standard sample.
[0067] Further, the luminescence (phosphorescence) life referred to
herein is based on values measured according to the following
method.
<<Method of Measurement of Life>>
[0068] A sample compound is dissolved in chloroform and spin-coated
onto a quartz substrate in a thickness of ca. 0.1 .mu.m and is
exposed to pulsative nitrogen laser light at an excitation
wavelength of 337 nm at room temperature by using a luminescence
life meter (made by Hamamatsu Photonics K.K.). After completion of
the excitation pulses, the decay characteristic of luminescence
intensity is measured.
[0069] When an initial luminescence intensity is denoted by
I.sub.0, a luminescence intensity after t(sec) is expressed
according to the following formula with reference to a luminescence
life .tau.(sec): I=I.sub.0exp(-t/.tau.).
[0070] Thus, the luminescence life .tau. is a time period in which
the luminescence intensity I is attenuated down to 1/e of the
initial intensity I (I/I.sub.0=e.sup.-1, e is a base of natural
logarithm).
[0071] A short phosphorescence life is a condition for providing an
EL device of a high luminescence efficiency. More specifically, a
long phosphorescence life means abundant presence of molecules in a
triplet excited state waiting for the luminescence leading to a
problem of a lowering in luminescence efficiency particularly at a
high current density. The material of the present invention is a
suitable luminescence material for an EL device because of a high
phosphorescence yield and a short phosphorescence life. Further, it
is assumed that because of a short phosphorescence life, the
duration at a triplet state is shortened to suppress the
concentration extinction. A high stability of the luminescence
material of the present invention was also exhibited in an actual
current conduction test of actual devices.
[0072] In the case of a phosphorescent material, the luminescence
characteristic thereof is severely affected by its molecular
environment. In the case of a fluorescence device, the basic
property of a luminescence material is examined based on
photoluminescence. In the case of phosphorescence, however, the
photoluminescence performance does not directly lead to the
luminescence performance of an EL device since it is frequently
affected by the polarity of host molecules, temperature and
solid/liquid state. As a result, EL device performances except for
a part thereof cannot be estimated from the photoluminescence
result.
[0073] In the case of a ligand of the present invention having a
cyclic group having one or plural fluorine atoms, it becomes
possible to shift the luminescence wavelength to a shorter side or
a longer side because of a change in the energy gap. If it is
assumed for convenience that HOMO/LUMO of metal electron orbits and
HOMO/LUMO of ligand electron orbits can be considered separately,
it is understood that HOMO/LUMO energy levels of ligand electron
orbits are changed by fluorine atoms having a large
electro-negativity to change the energy gap between the HOMO level
of the metal and the LUMO level of the ligand, thereby shifting the
luminescence from the MLCT state as the lowest excited state to a
shorter wavelength side or a longer wavelength side. Accordingly,
while a luminescence material exhibiting a stably high quantum
yield over a broad wavelength range (blue to red) has not been
found, it can be realized by a luminescence material of the present
invention, thus being able to provide a luminescence material,
which shows a high efficiency at a desired emission wavelength over
a broad wavelength range (from blue to red).
[0074] When a device is formed, due to a large electronegativity of
fluorine atoms, the inter-molecular interaction is suppressed to
physically result in a suppressed crystallinity favoring a uniform
film formation and physically suppressing the dimerization reaction
to prohibit the energy deactivation leading to an improved
luminescence efficiency, thus resulting in an improved electrical
property and an improved device stability.
[0075] Further, in the case of using a ligand containing a
plurality of fluorine atoms or polyfluoroalkyl groups as
substituents, it is considered that a direct interaction between
luminescence molecules is suppressed due to electrical repulsion
caused by their electrical effect or due to steric hindrance,
thereby preventing energy deactivation and concentration
extinction.
[0076] Further, from the viewpoint of device preparation, a
luminescence material having a substituent, particularly a
fluorinated substituent, allows easier vacuum deposition due to a
sublimation temperature decrease in the film formation by vacuum
deposition, thus providing a great advantage.
[0077] As a result, as shown in the Examples hereinafter, by using
a luminescence material having a substituent according to the
present invention, a stable luminescence for many hours with
suppressed concentration extinction can be expected. Further, it
becomes possible to attain a high phosphorescence yield over a
temperature range of -20.degree. C. to 60.degree. C. as an actual
operation temperature range of an organic luminescence device.
Further, in the case of using a compound at a concentration of 8
wt. % or higher with respect to a host material in the luminescence
layer or at a concentration higher than a compound having no
substituent, it becomes possible to provide an EL device exhibiting
excellent luminescence performance while suppressing the
concentration extinction. The concentration of the luminescence
material of the present invention in the luminescence layer may be
at least 8 wt. %, preferably 10 wt. % or higher, but the
luminescence material potentially has a possibility of being used
even at 100% without causing substantial concentration
extinction.
[0078] Herein, the term "luminescence performance" refers to a
characteristic attributable to a maximum luminescence efficiency
that can be expressed as any of a maximum luminance, a maximum of
luminance/current, a maximum of light flux/power consumption or a
maximum of external quantum yield.
[0079] A high-efficiency luminescence device according to the
present invention is applicable to a product requiring energy
economization or a high luminance. More specifically, the
luminescence device is applicable to a display apparatus, an
illumination apparatus, a printer light source or a backlight for a
luminescence layer display apparatus. As for a display apparatus,
it allows a flat panel display which is light in weight and
provides a highly recognizable display at a low energy consumption.
As a printer light source, the luminescence device of the present
invention can be used instead of a laser light source of a laser
beam printer. Independently addressable devices are arranged in an
array form to effect a desired exposure on a photosensitive drum
thereby forming an image. The apparatus volume can be remarkably
reduced by using the devices of the present invention. For the
illumination apparatus or backlight, the energy economization
effect according to the present invention can be expected.
[0080] For the application to a display, a drive system using a
thin-film transistor (abbreviated as TFT) drive circuit according
to an active matrix scheme may be used. By driving a display panel
using a luminescence material of the present invention in a
luminescence layer, it becomes possible to allow a stable display
for many hours with a good picture quality.

[0082] Hereinbelow, the present invention will be described more
specifically based on Examples.
[0083] Iridium metal coordination compounds used in Examples were
synthesized along synthesis paths shown below. (Analogous reactions
are described in Inorg. Chem. 1994, 33, p. 545).
Synthesis of Iridium Metal Coordination Compound
[0084] A process scheme for synthesizing iridium complexes used in
the present invention is shown below: ##STR13##
EXAMPLE 1
Synthesis of Example Compound No. 729
[0085] ##STR14##
[0086] In a 100 ml-three-necked flask, 3.18 g (24.9 mmol) of
thienylboronic acid, 5.65 g (25.0 mmol) of
1-bromo-4-trifluoromethylpyridine, 25 m of toluene, 12.5 ml of
ethanol and 25 ml of 2M-sodium carbonate aqueous solution, were
placed and stirred at room temperature under a nitrogen stream,
followed by addition of 0.98 g (0.85 mmol) of
tetrakis(triphenylphosphine)palladium (0). Thereafter, the system
was refluxed under stirring and nitrogen stream for 8 hours. After
completion of the reaction, the reaction product was cooled and
extracted by adding cold water and toluene. The organic layer was
washed with saline water and dried on magnesium sulfate, followed
by removal of the solvent under a reduced pressure to provide dry
solid. The residue was purified by silica gel column chromatography
(eluent: chloroform/methanol=10/1) to obtain 4.20 g (yield=74%) of
Compound A.
[0087] In a 100 ml-four-necked flask, 50 ml of glycerol was placed
and heated for 2 hours at 130-140.degree. C. under stirring and
bubbling with nitrogen. The glycerol was cooled to room temperature
and poured into 300 ml of 1N-hydrochloric acid, and the precipitate
was filtered out and washed with water. The precipitate was then
purified by silica gel chromatography with chloroform as eluent, to
obtain 0.33 g (yield: 38%) of red powdery Example Compound No.
729.
[0088] A toluene solution of the compound exhibited a luminescence
spectrum showing .lamda.max=563 nm. The compound was subjected, to
MALDI-TOF (matrix-assisted laser desorption ionization
time-of-flight mass spectroscopy) by using an apparatus
("REFLEX-III", made by Bruker Co.). In the method, an ion obtained
by removing one electron from a sample substance is subjected to
measurement of a mass thereof, so that the measured mass is denoted
by M.sup.+, and the method is frequently used for identification of
a substance. The measured M.sup.+ value was 877.0 from which the
objective product was confirmed.
[0089] For confirmation of phosphorescence-type luminescence, the
Example Compound was dissolved in chloroform, and the solution was
separately aerated with oxygen or nitrogen, each followed by
photoirradiation for comparison of photoluminescence. As a result,
substantially no luminescence attributable to the iridium complex
was recognized with respect to the oxygen-aerated solution, whereas
photoluminescence was confirmed with respect to the
nitrogen-aerated solution. From these results, the compound of the
present invention was confirmed to be a phosphorescent compound.
For reference, in the case of a fluorescent material, luminescence
attributable to the compound does not disappear even in an
oxygen-aerated solution.
[0090] Further, in contrast with a fluorescent material generally
showing a luminescence life of several nsec to several tens of
nsec, the compounds of the present invention including those
obtained in the following Examples, all exhibited a phosphorescence
life of 100 nsec or longer.
EXAMPLE 2
[0091] Example Compound No. 310 was synthesized through a similar
process as in Example 1.
[0092] Luminescence of toluene solution: .lamda.max=489 nm
[0093] MALDI-TOF MS: M.sup.+=859.1
EXAMPLE 3
[0094] Example Compound No. 238 was synthesized through a similar
process as in Example 1.
[0095] Luminescence of toluene solution: .lamda.max=515 nm
[0096] MALDI-TOF MS: M.sup.+=709.1
EXAMPLE 4
[0097] Example Compound No. 242 was synthesized through a similar
process as in Example 1.
[0098] Luminescence of toluene solution: .lamda.max=471 nm
[0099] MALDI-TOF MS: M.sup.+=763.1
EXAMPLE 5
[0100] Example Compound No. 384 was synthesized through a similar
process as in Example 1.
[0101] Luminescence of toluene solution: .lamda.max=466 nm
[0102] MALDI-TOF MS: M.sup.+=913.1
EXAMPLE 6
[0103] Example Compound No. 777 was synthesized through a similar
process as in Example 1.
[0104] Luminescence of toluene solution: max=696 nm
[0105] MALDI-TOF MS: M.sup.+=1231.1
EXAMPLE 7
[0106] Example Compound No.472 was synthesized. ##STR15##
[0107] In a 100 ml-two-necked flask, 60 ml of ethoxyethanol and 20
ml of H.sub.2O were placed and stirred for 1 hour under bubbling
with nitrogen. Then, 0.51 g (4.4 mmol) of Compound C and 0.71 g
(2.0 mmol) of iridium (III) trichloride hydrate were added, and the
system was heated for 16 hours around 100.degree. C. under stirring
and nitrogen stream. The reaction product was cooled to room
temperature and poured into 100 ml of water, followed by recovery
by filtration and washing with water of the precipitate. The
precipitate was then poured into 60 ml of ethanol and stirred for 1
hour, followed by filtering-out and washing with acetone, to obtain
0.95 g (yield: 89%) of yellow powdery Compound D. ##STR16##
[0108] In a 100 ml-two-necked flask, 50 ml of ethoxyethanol was
placed and stirred for 1 hour under bubbling with nitrogen. Then,
0.536 g (0.5 mmol) of Compound D, 0.17 g (1.4 mmol) of Compound E
and 0.75 g of sodium carbonate Na.sub.2CO.sub.3 were added, and the
system was heated for 16 hours around 100.degree. C. under stirring
and nitrogen stream. The reaction product was cooled to room
temperature and poured into 100 ml of water, followed by
filtering-out and washing with water of the precipitate. The
precipitate was poured into 70 ml of ethanol, and after stirring
for 1 hour, the precipitate was filtered out and dissolved in
chloroform, followed by filtration. The resultant filtrate was
condensed, and purified by silica gel column chromatography with
chloroform as eluent to obtain 0.45 g (yield: 73%) of yellow
powdery Example Compound No. 472. A toluene solution of the
compound exhibited a luminescence spectrum showing .lamda.max=526
nm. The compound exhibited M.sup.+=614.2 according to MALDI-TOF MS
and was confirmed to be the objective product.
EXAMPLE 8
[0109] In this Example, a device (effective display area=3
mm.sup.2) having a device structure including 4 organic layers as
shown in FIG. 1(c) was prepared. An alkali-free glass sheet was
used as a transparent substrate 15 and a 100 nm-thick indium tin
oxide (ITO) film was formed by sputtering and patterned as a
transparent electrode 14. Further, .alpha.-NPD represented by the
above-mentioned structural formula was vacuum-deposited in a layer
thickness of 40 nm thereon as a hole-transporting layer 13. Then,
as an organic luminescence layer 12, the above-mentioned CBP as a
host material and Example Compound No. 729 (metal coordination
compound) in an amount of providing 8 wt. % were co-vacuum
deposited in a layer thickness of 30 nm. Further, as an exciton
diffusion-prevention layer 17, BCP was vacuum-deposited in a
thickness of 10 nm. Then, as an electron-transporting layer 16, the
above-mentioned Alq3 was subjected to resistance heating vacuum
deposition at a vacuum of 10.sup.-4 Pa to form an organic film in a
thickness of 30 nm.
[0110] On the above, as a lower layer of a metal electrode layer
11, an AlLi alloy film was disposed in a thickness of 15 nm, and a
100 nm-thick Al film was vacuum-deposited thereon to form a
patterned metal electrode 11 disposed opposite to the transparent
electrode 14 and having an electrode area of 3 mm.sup.2.
[0111] The performances of the thus-obtained EL device were
measured by using a micro-current meter ("4140B", made by
Hewlett-Packard Corp.) for a current-voltage characteristic and
"BM7" (made by Topcon K.K.) for an emission luminance.

[0115] A device was prepared in the same manner as in Example 8

[0116] Each device was supplied with an electric field of 12
volts/100 nm with the ITO side as the anode and the Al side as the
cathode to measure a luminance.
[0117] In order to remove factors for device deterioration due to
oxygen or water, the above measurement was performed in a dry
nitrogen flow after taking the device out of the vacuum
chamber.
[0118] The results of devices using the respective compounds are
shown in Table 3. As is understood from the results shown in Table
3, the maximum luminance concentration of Comparative Compound 729R
was clearly between 1% and 8%, whereas Example Compound No. 729
provided with a substituent exhibited a higher luminance at 8% than

EXAMPLE 41
[0189] Hereinbelow, two examples of display apparatus are
described. First, an example of preparation of a picture display
apparatus having an XY-matrix structure is described with reference
to FIG. 2.
[0190] On a glass substrate 21 measuring 150 mm-length, 150
mm-width and 1.1 mm-thickness, a ca. 100 nm-thick ITO film was
formed by sputtering and patterned into 100 lines of 100 .mu.m-wide
transparent matrix electrodes (anode side) with a spacing of 40
.mu.m as simple matrix electrodes. Then, a four-layered organic
compound layer 23 was formed thereon including a luminescence layer
12 containing one of the compounds synthesized in Examples 1-7 as a
guest compound.
[0191] Then, 100 lines of 100 .mu.M-wide metal electrodes 24 were
formed with a spacing of 40 .mu.m by mask vacuum deposition so as
to be perpendicular to the transparent electrodes by vacuum
deposition at a vacuum of 2.times.10.sup.-5 Torr. The metal
electrodes were formed as a lamination of 10 nm-thick layer of
Al/Li alloy (Li: 1.3 wt. %) and then 150 nm-thick layer of Al.
[0192] The thus-obtained 100.times.100-simple matrix-type Organic
EL devices were subjected to a simple matrix drive in a glove box
filled with nitrogen at voltages of 7 volts to 13 volts by using a
scanning signal of 10 volts and data signals of .+-.3 volts as
shown in FIG. 3. As a result of an interlaced drive at a frame
frequency of 30 Hz, luminescence pictures were confirmed for the
respective devices.
[0193] As a picture display apparatus, the high-efficiency
luminescence device of the present invention allows a light-weight
flat panel display with economized energy consumption and
high-recognizability: As a printer light source, the luminescence
devices of the present invention may be arranged in a line and
disposed in proximity to the photosensitive drum, to provide a line
shutter wherein the respective devices are driven independently
from each other to effect prescribed exposure on the photosensitive
drum. On the other hand, the energy consumption economization
effect is expected in application as an illumination device or a
backlight for a liquid crystal display apparatus.
[0194] For another application to a picture display device, it is
particularly advantageous to form an active matrix-type picture
display device equipped with thin film transistors (TFTs) instead
of the above-mentioned XY-matrix wiring. Hereinbelow, an active
matrix-type picture display device according to the present
invention will be described with reference to FIGS. 4 to 6.
[0195] FIG. 4 is a schematic plan view of such a panel.
Circumferentially outside the panel are disposed a drive circuit
comprising a power supply source and a scanning signal driver, and
a data signal driver as a display signal input means (called a
picture data supply means, which are respectively connected to
current supply lines, X-direction scanning lines called gate lines
and Y-direction lines called data lines. The scanning signal driver
sequentially selects the gate scanning lines, and in synchronism
therewith, picture signals are supplied from the data signal
driver. Display pixels are disposed at intersections of the gate
scanning lines and the data lines.
[0196] Next, a pixel circuit operation is described with reference
to an equivalent circuit. When a selection signal is applied to a
gate selection line, TFT1 is turned on so that a data signal is
supplied from a data signal line to a capacitor Cadd, thereby
determining the gate potential of TFT2, whereby a current is
supplied to an organic luminescence device (EL) disposed at each
pixel through a current supply line depending on the gate potential
of TFT2. The gate potential of TFT2 is held at Cadd during one
frame period, so that the current continually flows from the
current supply line to the EL device during the period. As a
result, luminescence is retained during one frame period.
[0197] FIG. 6 is a schematic view illustrating a sectional
structure of a TFT used in this Example. On a glass substrate, a
polysilicone p-Si layer is formed, and the channel, drain and
source regions are doped with necessary impurities, respectively.
Thereon, gate electrodes are formed via a gate insulating film, and
drain electrodes and source electrodes connected to the drain
regions and source regions, respectively, are formed. In this
instance, the drain electrodes and transparent pixel electrodes
(ITO) are connected through contact holes bored in an intervening
insulating film.
[0198] The active device used in the present invention need not be
particularly restricted, and can also be a single-crystal silicon
TFT, an amorphous silicon a-Si TFT, etc.
[0199] On the pixel electrodes, plural layers or a single layer of
organic luminescence layer may be disposed and metal electrodes as
cathode are sequentially laminated to provide an active-type
organic luminescence device.
INDUSTRIAL APPLICABILITY
[0200] As described above, a substituted metal coordination
compound having a high phosphorescence efficiency and a short
phosphorescence life can be used in a luminescence layer at a high
concentration relative to the host material while preventing
concentration extinction. As a result, according to the present
invention, it is possible to obtain an excellent luminescence
device showing high luminescence efficiency. The luminescence
device of the present invention is also excellent as a display
device.
