Description

COMPONENT FOR ORGANIC ELECTRONIC ELEMENT USING THE SAME AND AND EL ELECTRONIC DEVICE THEREOF

The present invention relates to a compound for an organic electric device, an organic electric device using the same, and an electronic device thereof.

In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic electric element using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer therebetween. The organic layer is often made of a multi-layer structure composed of different materials in order to increase the efficiency and stability of the organic electric device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer.

The material used as the organic material layer in the organic electric element may be classified into a light emitting material and a charge transport material such as a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like according to a function.

In the case of polycyclic cyclic compounds containing heteroatoms, the difference in characteristics depending on the material structure is very large and applied to various layers as a material of an organic electric device. In particular, band gaps (HOMO, LUMO), electrical properties, chemical properties, and physical properties are different depending on the number of rings, the fused position, and the type and arrangement of heteroatoms. This has been going on.

As a representative example, the following Patent Documents 1 to 4 report the performance according to hetero type and arrangement, substituent type, fused position, etc. with respect to the 5-cyclic ring compound in the polycyclic ring compound.

[Patent Document 1]: US Patent 5843607

[Patent Document 2]: Japanese Patent Laid-Open No. 1999-162650

[Patent Document 3]: Korean Laid-Open Patent 2008-0085000

[Patent Document 4]: US Patent Publication 2010-0187977

[Patent Document 5]: Korean Laid-Open Patent 2011-0018340

[Patent Document 6]: Korean Laid-Open Patent 2009-0057711

Patent Literature 1 and Patent Literature 2 used indolocarbazole cores in which the heteroatoms in the 5-membered ring compound consist only of nitrogen (N), and report an example using an aryl group substituted or unsubstituted with N of indolocarbazole. have. However, in the case of the preceding invention 1, there was only a simple aryl group in which an alkyl group, an amino group, an alkoxy group, etc. were substituted or unsubstituted as a substituent, and thus it was very insufficient to prove the substituent effect of the polycyclic cyclic compound. And use as a phosphorescent host material is not described.

PTL 3 and PTL 4 include pyridine, pyrimidine, triazine, etc., each containing an aryl group and N in an indolocarbazole for core having N heteroatoms in the same 5-ring ring compound as Patent Documents 1 and 2; Although substituted compounds are described, only examples of use for phosphorescent green host materials are described, and no performance is described for other heterocyclic compounds substituted in the indolocarbazole core.

Patent Document 5 describes nitrogen (N), oxygen (O), sulfur (S), carbon, etc. as a heteroatom in the 5-ring cyclic compound, but in the measurement data, only the examples using the same isotype heteroatoms are present. Thus, the performance characteristics of the 5-membered ring compound containing heteroatoms could not be confirmed.

Therefore, the above patent document does not describe a solution for low charge carrier mobility and low oxidative stability of the 5-ring cyclic compound including isotype heteroatoms.

When five-membered cyclic compound molecules are generally stacked, they have strong electrical interactions with more adjacent π-electrons, which are closely related to charge carrier mobility, especially in the NN-type homocyclic cyclic compound. When the molecules are stacked, the order of intermolecular molecules has an edge-to-face shape, whereas heterocyclic heterocyclic compounds having different heteroatoms have a pi-stacking structure in which molecular packing structures face each other in reverse directions. structure) has the face-to-face arrangement order between molecules. Asymmetrically arranged heteroatoms N which are responsible for this lamination structure It has been reported that the steric effect of substituted substituents causes relatively high carrier mobility and high oxidative stability. ( Org . Lett . 2008, 10 , 1199)

In patent document 6, the example used as a fluorescent host material with respect to various polycyclic ring compounds of 7 or more rings was reported.

As described above, development of the fused position, the number of rings, the arrangement of heteroatoms, and the characteristics of the polycyclic cyclic compound have not been sufficiently developed.

In particular, in the phosphorescent organic EL device using the phosphorescent dopant material, the LUIMO and HOMO levels of the host material have a great influence on the efficiency and lifespan of the organic EL device, which can efficiently control electron and hole injection in the emission layer. This is because it is possible to prevent a decrease in efficiency and a decrease in life due to charge balance control, dopant quenching, and light emission at the hole transport layer interface in the light emitting layer.

In the case of fluorescent and phosphorescent light emitting materials, researches on increasing efficiency and lifespan of organic electric devices using thermally activated delayed fluorescent (TADF) and Exciplex have been recently conducted. Especially, the method of transferring energy from the host material to the dopant material has been investigated. There is a lot of research going on.

The identification of energy transfer in the light emitting layer for the thermally activated delayed fluorescent (TADF) and exciplex can be easily identified by the PL lifetime (TRTP) method.

The time resolved transient PL (TRTP) method is a method of observing a decay time of a spectrum after a pulsed light source is irradiated to a host thin film. It is a measuring method. The TRTP measurement is a measurement method that can distinguish between fluorescence and phosphorescence, and energy transfer method, exciplex energy transfer method, and TADF energy transfer method within a mixed host material.

As such, there are various factors that affect efficiency and lifespan depending on the way energy is transferred from the host material to the dopant material, and the energy transfer method differs depending on the material. This is not enough. Therefore, the development of new materials is continuously required, and in particular, the development of the host material of the light emitting layer is urgently required.

The present invention has been proposed to solve the problems of the phosphorescent host material as described above, the charge balance control, efficiency and lifetime in the light emitting layer by adjusting the HOMO level for the host material of the phosphorescent organic electroluminescent device comprising a phosphorescent dopant Compound which can improve It aims at providing the organic electroluminescent element and its electronic device using the same.

The present invention combines a specific first host material with a specific second host material as a main component to control efficient hole injection in the light emitting layer of the phosphorescent organic electroluminescent device, thereby reducing the energy barrier between the light emitting layer and the adjacent layer. It is possible to maximize the charge balance in the light emitting layer to provide high efficiency and long life of the organic electric device.

The present invention provides an organic electric device comprising a first electrode, a second electrode, and an organic material layer formed between the first electrode and the second electrode, wherein the organic material layer includes a light emitting layer, and the light emitting layer is represented by the following formula (1): Provided is an organic electric device comprising a first host compound represented by) and a second host compound represented by the following formula (2).

As can be seen from the results of Table 6, when the organic electroluminescent device material of the present invention represented by Formula 1 and Formula 2 is mixed and used as a phosphorescent host (Examples 1 to 100), a device using a single material (comparatively) Compared with Examples 1-7, it was confirmed that the driving voltage, efficiency and lifespan were significantly improved. In detail, the compounds of the present invention (3-6, 3-61, 3) in Comparative Examples 1 to 7 using the compound of the present invention represented by the general formula (2) and Comparative Compounds 1 to 4 as the phosphorescent host alone It was confirmed that Comparative Examples 1 to 3) using -74) exhibited higher efficiency and higher lifetime than Comparative Examples 4 to 7 using the comparative compound.

In addition, Comparative Examples 8 and 9, which are used as a phosphorescent host by mixing Comparative Compound 1, Comparative Compound 2 or Comparative Compound 3, and Comparative Compound 4 than Comparative Examples 1 to 7 using the single substance, show higher efficiency. I could confirm that. Comparing Comparative Example 8 and Comparative Example 9, a heterocyclic polycyclic compound having heteroatoms (N, S) different from each other in the 5-ring cyclic compound is compared to Comparative Example 8 in which a 5-ring heterocyclic compound having the same nitrogen atom is mixed. It was confirmed that Comparative Example 9 using the mixture included showed a higher efficiency. And compared to the case of Comparative Example 1 to Comparative Example 9 it was confirmed that Example 1 to Example 100 used as a host by mixing the compound of the present invention compound of Formula 1 and Formula 2 exhibited significantly higher efficiency and life, It was confirmed that the driving voltage was shown.

The inventors of the present invention determine that each of the substances of the compound of Formula 1 and the compound of Formula 2 have new characteristics other than those of the substances, based on the experimental results, the substance of Formula 1, the substance of Formula 2 , PL lifetime was measured using the mixture of the present invention. As a result, when the compounds of the present invention were mixed with Chemical Formula 1 and Chemical Formula 2, it was confirmed that a new PL wavelength was formed differently from a single compound. It was confirmed that the decrease and disappearance time increased from about 60 times to as much as about 360 times. This means that when the compounds of the present invention are used in combination, not only electrons and holes move through the energy levels of the respective materials, but also electrons, hole movements or energy due to exciplexes having new energy levels formed by mixing. The transmission is believed to increase efficiency and lifetime. As a result, when using the mixture of the present invention it can be said that the mixed thin film is an important example showing the exciplex energy transfer and the light emission process.

In addition, the combination of the present invention is superior to Comparative Examples 8 to 9 used as phosphorescent hosts mixed with a comparative compound because of the hole characteristics in the polycyclic compound represented by Formula 2 having characteristics such as stability as well as hole and high T1. When the compound represented by Formula 1 is mixed, the electron blocking ability is improved due to the high T1 and the high LUMO energy value, and more holes are quickly and easily moved to the light emitting layer. As a result, the charge balance in the light emitting layer of holes and electrons is increased, so that light emission is achieved inside the light emitting layer rather than at the hole transport layer interface, and thus deterioration is also reduced at the HTL interface, thereby maximizing driving voltage, efficiency, and lifetime of the device. . In addition, among the compounds represented by Formula 1, the compound substituted with dibenzofuran showed the best results in terms of driving voltage, efficiency, and lifetime, and the compound substituted with Dibenzothiophen was also excellent in terms of efficiency due to high refractive index. there was. In other words, it is concluded that the combination of Chemical Formula 1 and Chemical Formula 2 has an electrochemical synergy to improve the performance of the entire device.

As shown in Table 8, the mixture of the compound of the present invention was measured by manufacturing a device by ratio (2: 8, 3: 7, 4: 6, 5: 5). In detail, the results of the mixture of compound 1-33 'and compound 3-61 showed similarly excellent driving voltage, efficiency and lifetime for 2: 8 and 3: 7, but with 4: 6, 5: 5 As the ratio of the first host increases, the results of the driving voltage, the efficiency and the lifespan are gradually decreased, which is the same in the mixture of Compound 1-50 'and Compound 3-6. This may be explained because the charge balance in the light emitting layer is maximized when an appropriate amount of the compound represented by Chemical Formula 1 having strong hole characteristics such as 2: 8 and 3: 7 is mixed.
