Description

Aromatic amine compound and organic electroluminescent device thereof Technical Field The invention relates to the technical field of organic photoelectric materials, in particular to an arylamine compound and an organic electroluminescent device thereof. Background The Organic electroluminescent material is a core functional carrier of an Organic LIGHT EMITTING Diode (OLED), and its performance directly determines the luminous efficiency, working stability and service life of the device. The OLED has become a core technology in the display and illumination fields by virtue of the characteristics of self-luminescence, fast response speed, customizable flexibility and the like, and is widely applied to smart phone display screens, flexible display panels, novel illumination light sources and other scenes. The OLED is mainly composed of an electrode material film layer and an organic functional material layer. When a proper voltage is applied, holes start from the anode and sequentially pass through the hole injection layer and the hole transport layer to finally reach the light-emitting layer, and electrons start from the cathode and reach the light-emitting layer through the electron injection layer and the electron transport layer. The two carriers are combined in the light-emitting layer to form excitons, the excitons transfer energy to the organic light-emitting molecules to promote the transition from a low-energy ground state to a high-energy excited state, then the molecules fall back to the ground state in a radiation transition mode, and the energy is released in a light form, so that the light emission of the OLED is realized. In a functional layer system of an organic electroluminescent device, the existing hole transport material has the problem of low hole mobility, and the unbalance of electron and hole transport causes that excitons are difficult to efficiently recombine in a luminescent layer, thereby reducing the luminous efficiency of the device and shortening the service life of the device. Most of the main materials have poor bipolar transmission performance, the HOMO/LUMO energy level is not matched with a hole transmission layer, an electron transmission layer and a luminescent doping agent sufficiently, exciton quenching is easy to occur, the refractive index regulation interval of the existing coating material is narrow, the refractive index matching performance with a device substrate and a packaging layer is poor, the light extraction efficiency is improved, the glass transition temperature is low, deformation is easy to occur in the preparation and working processes of the device, and the interface stability and long-term optical performance are damaged. Therefore, in order to solve the above problems, a high-performance hole transport layer material, a light emitting layer host material and a capping layer material are developed to solve the problems of unbalanced carrier transport, low exciton utilization rate, insufficient light extraction efficiency and the like, and have a key meaning for promoting the high-performance and large-scale application of the OLED device.
