BACKGROUND

Technical Field

[0002] The present invention relates to compounds for organic electric elements, organic electric elements comprising the same, and electronic devices thereof.

Background Art

[0003] In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy of an organic material. An organic electric element utilizing the organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. In many cases, the organic material layer has a multi-layered structure having respectively different materials in order to improve efficiency and stability of an organic electric element, and for example, may include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like.

[0004] Materials used as an organic material layer in an organic electric element may be classified into a light emitting material and a charge transport material, for example, a hole injection material, a hole transport material, an electron transport material, an electron injection material, and the like according to its function.

[0005] Further, the light emitting material may be divided into a high molecular weight type and a low molecular weight type according to its molecular weight, and may also be divided into a fluorescent material derived from excited singlet states of electron and a phosphorescent material derived from excited triplet states of electron according to its light emitting mechanism. Further, the light emitting material may be divided into blue, green, and red light emitting material and yellow and orange light emitting material required for better natural color reproduction according to its light emitting color.

[0006] Meanwhile, when only one material is used as a light emitting material, there occur problems of shift of a maximum luminescence wavelength to a longer wavelength due to intermolecular interactions and lowering of the efficiency of a corresponding element due to a deterioration in color purity or a reduction in luminous efficiency. On account of this, a host/dopant system may be used as the light emitting material in order to enhance the color purity and increase the luminous efficiency through energy transfer. This is based on the principle that if a small amount of dopant having a smaller energy band gap than a host forming a light emitting layer is mixed in the light emitting layer, then excitons generated in the light emitting layer are transported to the dopant, thus emitting light with high efficiency. With regard to this, since the wavelength of the host is shifted to the wavelength band of the dopant, light having a desired wavelength can be obtained according the type of the dopant.

[0007] Currently, the power consumption is required more than more as size of display becomes larger and larger in the portable display market. Therefore, the power consumption is a very important factor in the portable display with a limited power source of the battery, and efficiency and life span issue also is solved.

[0008] Efficiency, life span, driving voltage, and the like are correlated with each other. For example, if efficiency is increased, then driving voltage is relatively lowered, and the crystallization of an organic material due to Joule heating generated during operation is reduced as driving voltage is lowered, as a result of which life span shows a tendency to increase. However, efficiency cannot be maximized only by simply improving the organic material layer. This is because long life span and high efficiency can be simultaneously achieved when an optimal combination of energy levels and T.sub.1 values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers included in the organic material layer is given.

[0009] In addition, in the recent organic electroluminescent devices, an emission-auxiliary layer (multi-layered hole transport layer) must be present between the hole transport layer and the light emitting layer in order to solve the problems of luminescence in the hole transport layer and the driving voltage, and it is necessary to develop different emission-auxiliary layers according to respective light emitting layers.

[0010] In general, an electron is transferred from an electron transport layer to a light emitting layer and a hole is transferred from a hole transport layer to the light emitting layer, as a result, an exciton is formed by the recombination of the electron and hole within the light emitting layer. However, material used in a hole transport layer has a low T1 value because the material should have a low HOMO value. As a result, the exciton generated in the light emitting layer is transferred to the hole transport layer and it causes charge unbalance in the light emitting layer, thereby emitting light at the interface of the hole transport layer.

[0011] When light is emitted from the interface of the hole transporting layer, the color purity and efficiency of the organic electric element are lowered and the lifetime is shortened. Therefore, it is strongly desired to develop materials for the emission-auxiliary layer having a HOMO level between the HOMO energy level of the hole transporting layer and the HOMO energy level of the light emitting layer, a high T1 energy value and a hole mobility within a suitable driving voltage range (within a driving voltage range of blue element of a full device).

[0012] However, this cannot be achieved simply by the structural properties of the core of the emission-auxiliary layer material. An element having a high efficiency and a long life span can be realized when the characteristics of core and sub-substituents of the emission-auxiliary layer material, the proper combination of the emission-auxiliary layer and the hole transport layer, and the proper combination of the emission-auxiliary layer and the light emitting layer.

[0013] In order to fully exhibit the excellent characteristics of the organic electric element, materials forming the organic material layer in the element, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, an emission-auxiliary layer material, etc. should be prerequisite to support by a stable and efficient material, and in particular, it is strongly required to develop material of host of a light emitting layer, a hole transport layer and an emission-auxiliary layer.

##STR00006##

[0028] Hereinafter, referring to the FIGURE, a lamination structure of an organic electric element including the compound of the present invention will be described.

[0029] The FIGURE illustrates an organic electric element according to an embodiment of the present invention.

[0030] Referring to the FIGURE, an organic electric element 100 according to an embodiment of the present invention includes a first electrode 120 formed on a substrate 110, a second electrode 180, and an organic material layer formed between the first electrode 120 and the second electrode 180 and comprising the compound of the present invention. Here, the first electrode 120 may be an anode (positive electrode), and the second electrode 180 may be a cathode (negative electrode). In the case of an inverted organic electric element, the first electrode may be a cathode, and the second electrode may be an anode.

[0031] The organic material layer may include a hole injection layer 130, a hole transport layer 140, a light emitting layer 150, an electron transport layer 160, and an electron injection layer 170 formed in sequence on the first electrode 120. Here, at least one layer of the organic material layer may be omitted, or the organic material layer may further include a hole blocking layer, an electron blocking layer, an emission-auxiliary layer 151, an electron transport auxiliary layer, a buffer layer 141, etc., and the electron transport layer 160 or the like may serve as the hole blocking layer.

[0032] In addition, although not shown, the organic electric element according to an embodiment of the present invention may further include at least a protective layer or a layer for improving luminous efficiency. The layer for improving luminous efficiency may be formed on a surface that does not face the organic material layer of both surfaces of the first electrode or the second electrode.

[0033] The inventive compound employed in the organic material layer may be used as a material of a hole injection layer 130, a hole transport layer 140, an emission-auxiliary layer 151, an electron transport auxiliary layer, an electron transport layer 160, an electron injection layer 170 and the like, as a host or a dopant material of a light emitting layer 150, or as a material of a layer for improving luminous efficiency. For example, the compound according to Formula 1 of the present invention may be used as material of the light emitting layer 150, preferably, as host material of the light emitting layer 150, a mixture of the compound according to Formula 1 of the present invention and the compound according to Formula 12 of the present invention may be used as host material, and the compound according to Formula 20 of the present invention may be used as material of a hole transport layer or an emission-auxiliary layer. Preferably, the compound represented by Formula 21 or 22 of the present invention may be used as material of a hole transport layer, and the compound represented by Formula 23 or 24 of the present invention may be used as material of an emission-auxiliary layer.

[0034] Even if the core is the same core, the band gap, the electrical characteristics, the interface characteristics, and the like may be different depending on which substituent is bonded at which position. Therefore, it is necessary to study the selection of the core and the combination of the core and the sub-substituent bonded to the core. Specially, long life span and high efficiency can be simultaneously achieved when the optimal combination of energy levels and T.sub.1 values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers of an organic material layer is achieved.

[0035] Therefore, according to the present invention, energy level and T.sub.1 value between the respective layers of the organic material layer, inherent material properties (mobility, interfacial properties, etc.) and the like can be optimized by using as a host material of a light emitting layer a single compound represented by the Formula 1 or a mixture of the compound represented by the Formula 1 and the compound represented by the Formula 12, by using these compounds as a light-emitting layer material and simultaneously using the compound according to the formula 20 as a hole transport layer or an emission-auxiliary layer, and thus it is possible to simultaneously improve the life span and efficiency of the organic electric element.

[0036] The organic electric element according to an embodiment of the present invention may be manufactured using various deposition methods. The organic electric element according to an embodiment of the present invention may be manufactured using a PVD (physical vapor deposition) method or CVD (chemical vapor deposition) method. For example, the organic electric element may be manufactured by depositing a metal, a conductive metal oxide, or a mixture thereof on the substrate to form the anode 120, forming the organic material layer including the hole injection layer 130, the hole transport layer 140, the light emitting layer 150, the electron transport layer 160, and the electron injection layer 170 thereon, and then depositing a material, which can be used as the cathode 180, thereon. Also, an emitting auxiliary layer 151 may be formed between a hole transport layer 140 and a light emitting layer 150, and an electron transport auxiliary layer may be formed between a light emitting layer 150 and an electron transport layer 160.

[0037] Also, the organic material layer may be manufactured in such a manner that a smaller number of layers are formed using various polymer materials by a soluble process or solvent process, for example, spin coating, nozzle printing, inkjet printing, slot coating, dip coating, roll-to-roll, doctor blading, screen printing, or thermal transfer, instead of deposition. Since the organic material layer according to the present invention may be formed in various ways, the scope of protection of the present invention is not limited by a method of forming the organic material layer.

[0038] The organic electric element according to an embodiment of the present invention may be of a top emission type, a bottom emission type, or a dual emission type depending on the material used.

[0039] Also, the organic electric element according to an embodiment of the present invention may be any one of an organic light emitting diode, an organic solar cell, an organic photo conductor, an organic transistor, and an element for monochromatic or white illumination.

[0291] After 2-TNATA was vacuum-deposited on the ITO layer formed on a glass substrate to form a hole injection layer with a thickness of 60 nm, the compound 14-69 of the present invention was vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 60 nm. Next, the compound 14-72 of the present invention was vacuum-deposited to a thickness of 20 nm on the hole transport layer to form an emission-auxiliary layer and a light emitting layer with a thickness of 30 nm was vacuum-deposited on the hole transport layer by using a mixture of the compound 1-1(the first host) and the compound 5-27(the second host) of the present invention at 6:4 as a host material and Ir(ppy).sub.3) as a dopant material in a weight ratio of 95:5.

And, the T95 life time was measured using a life time measuring apparatus manufactured by Mcscience Inc. at reference brightness of 5000 cd/m.sup.2. The measurement results are shown in Tables 11 below.

[0295] From Tables 5 to 8, it can be seen that the driving voltage of the organic electroluminescent device can be lowered and the luminous efficiency and lifespan are significantly improved when the material for an organic electroluminescent device of the present invention is used as a phosphorescent host material.

[0296] In particular, referring to Table 5, it can be seen that even when the compound represented by Formula 1 of the present invention is used as a single host, device characteristics are superior to that using a comparative compound.

[0297] These results can be explained by the LUMO value of Compound 1-1 of the present invention. Referring to Table 9A below, it can be seen that the LUMO level of Comparative Compound 2 is the highest, the LUMO level of Comparative Compound is the lowest, and the LUMO level of Compound 1-1 of the present invention is located in the middle.

TABLE-US-00012 TABLE 9A comp. Com2 comp. Com3 Com. 1-1 LUMO 1.939 1.839 1.877

[0298] When comparing Comparative Compounds 2 and 3, Comparative Compound 2 is different in that the heteroatom of both heterocycles attached to the triazine is S, while in case of Comparative Compound 3, the heteroatom is O. From Table 9 above, it can be seen that when heteroatoms S are introduced into both heterocycles, the LUMO value is highest (comparative compound 2), and when O is introduced, the LUMO value is lowest (comparative compound 3), the LUMO value is located in the middle when S as a heteroatom is introduced into one heterocycle and O is introduced into the other heterocycle as the compound of the present invention.

[0299] When comparative compound 2 having the highest LUMO level is used as the phosphorescent host material, the LUMO level is too high, and thus the LUMO level acts as a barrier to electron movement. Therefore, the electron transfer from the electron transport layer to the light emitting layer is not easy, and the charge balance in the light emitting layer is reduced.

[0300] In addition, when comparative compound 3 having the lowest LUMO level is used as a phosphorescent host material, the energy gap between the electron transport layer and the LUMO level becomes too large, so that electrons cannot be smoothly transferred from the electron transport layer to the light emitting layer, as a result, the charge balance within the light emitting layer is reduced.

[0301] On the other hand, when the compound of the present invention in which the LUMO level is located in the middle of the LUMO level of the comparative compounds is used as a phosphorescent host material, it has an appropriate LUMO level for electron transfer, so the biased electron transfer characteristics of Comparative Compound 2 and Comparative Compound 3 can be complemented. Therefore, when the compound of the present invention is used as a phosphorescent host material, the charge balance in the light-emitting layer increases, so that the luminous efficiency and lifetime of the organic electroluminescent device are improved.

[0302] In Table 9A, compound 1-1 of the present invention is used as an example, but the same conclusion can be reached with the compounds of the present invention used in Examples 2 to 15 as a phosphorescent host material.

[0303] On the other hand, referring to the device results of the embodiments of the present invention, it can be seen that performance is improved in all aspects of driving voltage, efficiency, and lifetime when 1-dibenzofuran is substituted rather than 4-dibenzofuran, and when 2-position of 1-dibenzofuran is substituted rather than 4-position.

[0304] In more detail, it can be seen that the device result of Example 5 in which 1-dibenzofuran is substituted in triazine is better than Example 1 in which 4-dibenzofuran is substituted in triazine, and the electrical properties of the device of Example 7 in which a substituent is attached at 2-position in benzene of 1-dibenzofuran instead of 4-position are improved.

[0305] This suggests that the energy level of the compound (HOMO, LUMO, T.sub.1, etc.) and deposition conditions (for example, T.sub.d, etc.) are changed because the physical properties of the compound change depending on the substitution position, and this acts as a major factor (e.g. energy balance) in improving device performance, which can lead to different device results.

[0306] The above description can be equally applied to the case of using one compound of the present invention as a host, as well as when using two or more hosts and even when used in combination with other layers.

[0307] In addition, as can be seen from the device measurement results of Examples 1, 2, 5 and 6 of the present invention, it can be seen that when a substituent (Ar.sub.2, Ar.sub.3) attached to a heterocycle (dibenzofuran, dibenzothiophene) attached to a triazine is mutually asymmetric, device performance is further improved. It is believed that when Ar.sub.2 and Ar.sub.3 are mutually asymmetric, due to the non-planarity of the compound, charges are appropriately localized and the flow of the conjugate system is effectively controlled to improve the lifetime of the device.

Next, compound G-1 of the present invention was vacuum-deposited to a thickness of 20 nm on the hole transport layer to form an emission-auxiliary layer and a light emitting layer with a thickness of 30 nm was vacuum-deposited on the hole transport layer by using 4,4'-N,N'-dicarbazole-biphenyl (hereinafter, "CBP") and Ir(ppy).sub.3) as a dopant material in a weight ratio of 95:5. Subsequently, BAlq was vacuum-deposited with a thickness of 10 nm on the light emitting layer to form a hole blocking layer, Alq.sub.3 was vacuum-deposited with a thickness of 40 nm on the hole blocking layer to form an electron transport layer. Next, LiF was deposited with a thickness of 0.2 nm on the electron transport layer to form an electron injection layer, and then Al was deposited with a thickness of 150 nm on the electron injection layer to form a cathode.

[0313] As can be seen from the results of Table 12, when a green organic electroluminescent device was manufactured by using the compounds of the present invention as material for an emission-auxiliary layer, the driving voltage of the organic electroluminescent device is lowered, and luminous efficiency and lifetime can be improved, compared to the comparative examples not forming an emission-auxiliary layer, or using Ref 1 to Ref 4 as material of an emission-auxiliary layer. That is, in the case of Comparative Examples 13 to 16 in which the emission-auxiliary layer was formed using one of the comparative compounds ref 1 to ref 4 rather than Comparative Example 12 in which an emission-auxiliary layer was not formed, the driving voltage, efficiency, and lifetime of the device were improved.

[0314] Ref 1, Ref 3 and Ref 4 differ in the substituents connected to the nitrogen atom of the amine group in the NPB type. A phenyl derivative (biphenyl) is attached to the nitrogen atom of the amine group in Ref 1, while diphenyl fluorene is attached to the nitrogen atom in Ref 3 and Ref 4. Looking at the device characteristics of Comparative Example 13, 15, and 16 using these compounds as material of an emission-auxiliary layer, it can be seen that the device characteristics of Comparative Example 15 and are superior to those of Comparative Example 13.

[0315] In addition, comparing Ref 2 and Ref 4, Ref 4 contains one additional amine group and carbazole is bound to the additional amine group, compared to Ref 2. Looking at the device characteristics of Comparative Example 14 and 16 using these compounds as material of an emission-auxiliary layer, it can be seen that efficiency and lifetime are similar, but the driving voltage is better in Comparative Example 14.

[0316] From these results, it can be seen that even if compounds having similar structures are used for devices, the characteristics of the devices may vary depending on the substitution position of the substituent and the type of the substituent. This seems to be due to differences in the properties of the compounds when they have different types of substituents and the position substituted, and due to these differences, the physical properties of the compound act as a major factor in improving device performance (e.g., energy balance) when depositing the compound in the device manufacturing process.

[0317] Comparing the compound of the present invention and Ref 3, it is the same in that the two amine groups are bonded through an arylene linking group, and diphenylfluorene is bonded to the nitrogen atom of the amine group, but there is a difference in that the position where the nitrogen of the amine group is bonded is reverse phenyl(i.e., refers to the phenyl of the diphenyl position rather than the fluorene backbone of the 9,9-diphenyl-fluorene structure) in case of the present invention, while the position is the backbone benzene in case of Ref 3. Due to this difference, it can be seen that the driving voltage, lifetime, and efficiency are significantly improved when the compound of the present invention is used as material of an emission-auxiliary layer, compared to Comparative Example 15 using Ref 3.

[0318] It appears that this is because the physical properties of the compound including LUMO, HOMO, band gap and T.sub.1 value are changed depending on where the amine group is attached to the diphenylfluorene and this difference in physical properties serves as a major factor influencing device characteristics when depositing a compound for forming an emission-auxiliary layer in a device manufacturing process.

[0319] In addition, comparing the device results of Examples 86, 90, 91, and 97 of the present invention, it can be seen that the driving voltage, efficiency, and lifetime of the device when a specific substituent other than a simple aryl group is substituted with a substituent of an amine group. That is, the device results of Examples 90 and 97 showed better values than Example 86, wherein a compound (G-27 or G-52) substituted with dibenzofuran or fluorene containing a hetero atom is used in Examples 90 and 97 and Compound G-1 in which a simple phenyl group was substituted with a substituent of an amine group was used as material of an emission-auxiliary layer in Example 86, and the device results of Examples 91 showed better values than Examples 90 and 97, wherein a compound G-29 in which fluorene and dibenzofuran are linked to one nitrogen atom of the amine group is used in Example 91.

[0320] Further, comparing Examples 100 and 106 of the present invention, it can be seen that the device results of Example 100 are further improved than Example 105, wherein fluorene-substituted compound G-101 at a nitrogen atom connected to diphenylfluorene is used as material of an emission-auxiliary layer in Example 105, and compound G-66 in which fluorene is substituted at a nitrogen atom of another amine group other than the nitrogen atom connected to diphenylfluorene is used as material of an emission-auxiliary layer in Example 100.

[0321] In addition, comparing Examples 86 and 102 of the present invention, it can be seen that the device results of Example 86 are further improved than Example 102 when two amine groups of the compound of the present invention are linked to each other through a phenyl linker, wherein a compound G-1 in which two amine groups are linked to the linker phenyl in a meta position is used as material of an emission-auxiliary layer in Example 86 and compound G-74 in which two amine groups are para-linked to phenyl is used as material of an emission-auxiliary layer in Example 102.

[0322] It appears that this is because when the structure of the compound is changed according to the type of substituent, the position of substitution and the method of substitution, the physical properties of the compound are changed, and as a result, physical properties are changed to improve the properties of the device when an emission-auxiliary layer is formed.
