Description

Technical Field

[0001] The invention relates to the technical field of organic photoelectric materials, and in particular to an aromatic amine compound and an organic electroluminescent device thereof. Background Art

[0002] With the continuous development of the information age, people have higher and higher requirements for information display technology. The response speed of liquid crystal displays is relatively slow and it is difficult to prepare large-area display devices with modern technology. Compared with liquid crystal displays, organic electroluminescent devices (OLED) displays have significant characteristics such as active luminescence, lightness, thinness, good contrast, no viewing angle restrictions, and low energy consumption. They have obvious advantages in the fields of display and lighting and have broad application prospects.

[0003] The structure of OLED devices is usually divided into single-layer devices, double-layer devices, three-layer devices and multi-layer devices. The typical OLED structure is to form HTL (hole transport layer), EML (light-emitting layer), ETL (electron transport layer), cathode, etc. on the anode. The working principle of OLED devices is that the holes and electrons emitted from the anode and cathode are injected into the organic layer of the device; the electrons and holes migrate from the hole transport layer and the electron transport layer to the light-emitting area of ​​the device respectively; the holes injected from the anode and the electrons injected from the cathode recombine in the light-emitting layer of the organic matter to form excitons; the excited state energy is transferred to the organic light-emitting substance; and it is transitioned from the ground state to the excited state. Because the energy of the excited state is unstable, the excited organic molecules will transition from the excited state to the ground state, and the luminescence phenomenon will occur after the radiation transition.

[0004] The basic function of the hole transport layer in the OLED device is to increase the transmission rate of holes in the device and effectively block electrons in the light-emitting layer to achieve maximum recombination between carriers and improve the luminous efficiency. At the same time, it reduces the energy barrier of holes in the injection process and improves the injection efficiency of holes, thereby improving the luminous efficiency of the device and extending the service life of the device. The function of the cover layer in the OLED device is to improve the light extraction efficiency, adjust the interference effect of light, and reduce the amount of light loss, thereby improving the luminous efficiency of the device and extending the service life of the device.

[0005] However, traditional hole transport materials and covering layer materials usually cannot provide satisfactory luminous efficiency and service life; therefore, how to design a type of hole transport material and covering layer material with high brightness, long life and low cost is a problem to be solved. Summary of the invention

[0006] In order to solve the above problems, the present invention aims to provide an aromatic amine compound and an organic electroluminescent device thereof, which can improve the luminous efficiency of the organic electroluminescent device and extend the service life of the device.
