Description

Compound for organic electric device, organic electric device using same, and 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, the organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy using an organic material. An organic electric device using an organic light emitting phenomenon usually has a structure including an anode and a cathode and an organic material layer therebetween. Here, the organic layer is often formed of a multi-layered structure composed of different materials in order to increase the efficiency and stability of the organic electric device, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer.

Lifespan and efficiency are the most problematic in organic electroluminescent devices, and as displays become larger, these problems of efficiency and lifespan must be solved.

Efficiency, lifespan, and driving voltage are related to each other, and when the efficiency is increased, the driving voltage is relatively decreased. It shows a tendency to increase the lifespan.

However, the efficiency cannot be maximized simply by improving the organic material layer. This is because, when the energy level and T1 value between each organic material layer, and the intrinsic properties of the material (mobility, interfacial properties, etc.) are optimally combined, a long lifespan and high efficiency can be achieved at the same time.

In general, electrons are transferred from the electron transport layer to the emission layer, and holes are transferred from the hole transport layer to the emission layer, and excitons are generated by recombination.

However, most of the materials used for the hole transport layer have a low T1 value because they should have a low HOMO value. As a result, excitons generated in the emission layer are transferred to the hole transport layer, resulting in charge unbalance in the emission layer. ) and emit light at the hole transport layer interface. When light is emitted at the hole transport layer interface, the color purity and efficiency of the organic electric device are lowered and the lifespan is shortened.

In order to solve the problem of light emission in the hole transport layer in recent organic electroluminescent devices, a light emitting auxiliary layer should exist between the hole transport layer and the light emitting layer, and different light emission auxiliary layers are developed according to each light emitting layer (R, G, B). is becoming

It should be supported by this, and in particular, it is necessary to develop materials for the hole transport layer and the light emitting auxiliary layer.

As can be seen from the results of Table 4, when a green organic light emitting device is manufactured using the material for an organic electroluminescent device of the present invention as a hole transport layer material, the compound of the present invention and the basic skeleton are similar to Comparative Compounds A to Comparison It is possible to improve the driving voltage, luminous efficiency, and lifespan of the organic light emitting diode compared to Comparative Examples using Compound D.

The comparative compounds A to D are similar to the compounds of the present invention in that spiroadamantane is substituted with an amine group, but the compounds of the present invention are different in that the group represented by formula A must be substituted.

Table 5 below shows the results of confirming the difference in the energy level of the compound according to the type of the substituent. In Table 5 below, the HOMO level was measured using the DFT method (B3LYP/6-31g(D)) of the Gaussian program.

HOMO (eV) Comparative compound A -4.770 Comparative compound B -4.793 Comparative compound C -4.715 P-1 -4.699

As can be seen from Table 5, the compound P-1 of the present invention has a higher HOMO value than the comparative compounds A to C. Therefore, when the hole transport layer is formed using the compound of the present invention, it has stronger hole characteristics than the comparative compound, and as a result, it seems to affect not only the driving voltage but also the improvement of device characteristics such as efficiency and lifespan.

Comparing the compound of the present invention with the comparative compound D, in the case of the comparative compound D, a substituent having a spiro ring moiety similar to that of the compound of the present invention is introduced, but in the case of the compound of the present invention, a moiety forming a spiro ring Since one of them contains C or a hetero element, the stability to electrons passing from the light emitting layer is increased than that of simple spirobifluorene, which seems to affect the overall performance of the device.

In addition, when a substituent having n = 0 of Formula A among the compounds represented by Formula 1 is introduced, the molecular planarity is lower than that of the comparative compounds, but the Tg value is decreased. Because this is possible, it seems to affect the overall performance improvement of the device.

Although Comparative Compounds A to D and the compounds of the present invention were composed of similar components, it was confirmed that the device using the compounds of the present invention improved the performance.

These results show that even for compounds having similar molecular structures, such as Comparative Compounds A to D and the compounds of the present invention, hole characteristics, light efficiency characteristics, and energy levels (HOMO, LUMO) depending on the type of substituent of the compound of the present invention , hole injection and mobility characteristics, the properties of the compound, such as the charge balance of holes and electrons, etc. are more suitable for the hole transport layer, which can lead to completely different results from the device characteristics of Comparative Examples 1 and 2 can be known

In addition, in the evaluation results of the above-described device fabrication, the device characteristics in which the compound of the present invention is applied to the hole transport layer has been described, but the compound of the present invention may be applied to one or more layers of the light emitting layer, the hole transport layer and the light emission auxiliary layer.
