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] In the early years, inorganic electroluminescent materials developed rapidly, and devices based on inorganic electroluminescent materials have been applied to optoelectronic and display electronic equipment, including instrument panels, electronic boards, advertising boards, etc. However, inorganic electroluminescent material devices have high production costs, difficult processing, low efficiency, and it is difficult to achieve large-area high-resolution flat panel displays. Organic electroluminescent devices (OLEDs) are currently a research hotspot in the field of organic optoelectronics because of their active luminescence, lightness, thinness, good contrast, no viewing angle restrictions, and low energy consumption. They have broad application prospects in the fields of flat panel displays and solid-state lighting.

[0003] The structure of an organic electroluminescent device starts from the cathode, followed by the electron transport region, the light-emitting layer, the hole transport region, and the anode. After a certain voltage is applied to the cathode and the cathode, charges begin to be injected, the anode injects holes, and the cathode injects electrons. The electrons and holes injected into the organic layer are called carriers. The carriers are transferred between the organic molecules in the functional transport layer and move to the light-emitting layer. The electrons and holes recombine in the light-emitting molecules to form excitons, and then the excitons migrate within a certain range to transfer energy. The molecules that capture energy are excited and transition from a stable state to an unstable excited state. When they return to the stable ground state, they release energy. The energy decays in the form of radiation photons, resulting in luminescence.

[0004] The hole transport layer is between the anode and the light-emitting layer. Its main function is to increase the hole transmission rate in the device and reduce the energy barrier of the hole during the injection process, thereby improving the hole injection efficiency, which helps to improve the brightness and luminous efficiency of the OLED device and extend the service life of the device. The role of the light-emitting layer in the OLED is to promote the recombination of electrons and holes in the light-emitting layer to form excitons. The main material of the light-emitting layer usually has a hole transport or electron transport function, which can efficiently transfer energy to the doping material, thereby improving the luminous efficiency of the device. By controlling the structure and composition of the light-emitting layer material, specific color emission can be achieved, thereby enhancing the color purity and brightness of the OLED, and protecting the device from environmental factors, thereby extending the service life of the device.

[0005] As people's requirements for OLED performance continue to increase, existing hole transport materials and light-emitting layer materials are difficult to meet the requirements of higher performance of devices. R&D personnel need to continuously develop and optimize the structure of hole transport materials and light-emitting layer materials to continuously improve the luminous efficiency and service life of OLEDs to meet the market needs of different application scenarios.
