Description

Compound for organic electric device, organic electric device using the same, and electronic device thereof {COMPOUND FOR ORGANIC ELECTRONIC ELEMENT USING THE SAME, AND AN 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 emission phenomenon refers to a phenomenon in which electrical energy is converted into light energy by using an organic material. An organic electric device using the organic light emission phenomenon has a structure including an anode, a cathode, and an organic material layer therebetween. Here, the organic material layer is often made of a multilayer structure composed of different materials in order to increase the efficiency and stability of the organic electronic device, and may be formed of, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like.

Materials used as an organic material layer in an organic electric device can be classified into light-emitting materials and charge transport materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials, according to their functions. And the light-emitting material can be classified into a high molecular type and a low molecular type according to the molecular weight, and according to the light emitting mechanism, it can be classified into a fluorescent material derived from the singlet excited state of the electron and a phosphorescent material derived from the triplet excited state of the electron. have. In addition, the light-emitting material may be classified into blue, green, and red light-emitting materials and yellow and orange light-emitting materials necessary to realize a better natural color according to the light-emitting color.

On the other hand, when only one material is used as a light-emitting material, the maximum light-emitting wavelength shifts to a long wavelength due to the interaction between molecules, and the color purity decreases or the efficiency of the device decreases due to the light-emitting attenuation effect.Therefore, the increase in color purity and energy transfer A host/dopant system may be used as a light-emitting material in order to increase the luminous efficiency through. The principle is that when a small amount of a dopant having an energy band gap smaller than that of the host forming the light emitting layer is mixed in the light emitting layer, excitons generated in the light emitting layer are transported to the dopant to emit light with high efficiency. At this time, since the wavelength of the host moves to the wavelength of the dopant, light having a desired wavelength can be obtained according to the type of dopant used.

Currently, the portable display market is increasing in size as a large-area display, and for this reason, power consumption that is greater than the power consumption required by the existing portable display is required. Therefore, power consumption has become an important factor for portable displays that have a limited power supply source, such as a battery, and efficiency and life issues are also important factors that must be solved.

Efficiency, lifespan, and driving voltage are related to each other. As the efficiency increases, the driving voltage decreases relatively, and as the driving voltage decreases, crystallization of organic materials by Joule heating generated during driving decreases. It shows a tendency to increase the lifespan. However, the efficiency cannot be maximized simply by improving the organic material layer. This is because the long life and high efficiency can be achieved at the same time when the optimum combination of the energy level and T1 value between each organic material layer and the intrinsic properties of the material (mobility, interfacial properties, etc.) is achieved.

In addition, in order to solve the problem of light emission in the hole transport layer in recent organic electroluminescent devices, a method of using a light emitting auxiliary layer between the hole transport layer and the light emitting layer is being studied. Since material properties are different, it is time to develop a light-emitting auxiliary layer for each light-emitting layer.

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

However, in the case of the material used for the hole transport layer, since it must have a low HOMO value, most have a low T1 value, and as a result, excitons generated in the light-emitting layer pass to the hole transport layer interface or the hole transport layer, and as a result, the hole transport layer interface. Light emission in the light emitting layer or charge unbalance in the light emitting layer is caused to 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 deteriorated, and the lifespan is shortened. Therefore, it must be a material having a HOMO level between the HOMO energy level of the hole transport layer and the HOMO energy level of the light emitting layer, has a high T1 value, and has a suitable driving voltage range (within the range of the driving voltage of the blue device of the full device). Mobility) is urgently required to develop a light emitting auxiliary layer.

However, this cannot be achieved simply due to the structural characteristics of the core of the light-emitting auxiliary layer material, and the characteristics of the core and sub-substituent of the light-emitting auxiliary layer material, and a suitable combination between the light-emitting auxiliary layer and the hole transport layer, and the light-emitting auxiliary layer and the light-emitting layer are made. When it is lost, a high-efficiency and high-life device can be implemented.

Meanwhile, development of materials for a light-emitting layer and a light-emitting auxiliary layer having stable properties, that is, a high glass transition temperature, against Joule heating generated when the device is driven is also required. The low glass transition temperature of the light-emitting layer and the light-emitting auxiliary layer material decreases the uniformity of the thin film surface when the device is driven, and the material may be deformed due to heat generated when the device is driven, which is reported to have a great effect on the life of the device.

Therefore, it is necessary to develop a material that can withstand a long time during evaporation, that is, a material with strong heat resistance, and materials that form the organic material layer in the device, such as hole injection materials, hole transport materials, and light emission, are required to fully exhibit the excellent characteristics of organic electronic devices. A material, an electron transport material, an electron injection material, and a light-emitting auxiliary layer material should be supported by a stable and efficient material. In particular, development of materials used for the light-emitting auxiliary layer and the light-emitting layer is urgently required.
