Zusammenfassung:The invention discloses an arylamine organic compound and application thereof, the structure of the arylamine organic compound is as shown in a general formula (1): the compound is a monoamine compound simultaneously containing benzo [4, 5] imidazo [1, 2-a] pyridine and derivatives thereof and benzoxazolyl or benzothiazolyl, and has relatively proper Eg energy level and thermal stability; the evaporation temperature is low, the decomposition temperature is higher than the evaporation temperature, the extinction coefficient at the wavelength of 380 nm is high, a high-energy external light source in an ultraviolet region can be effectively absorbed, and damage to organic materials in the organic light-emitting device is reduced to the maximum extent. The compound has a high refractive index in the visible light field, and can effectively improve the light extraction efficiency of an OLED device and reduce the angle dependence after being applied to the OLED device as a covering layer, thereby improving the lumi
