The invention provides a triarylamine compound and an organic light-emitting device thereof, belonging to the technical field of organic optoelectronic materials. The triarylamine compound of the present invention is a compound formed by bonding triarylamine, benzoxazole and/or benzothiazole and/or benzimidazole and/or benzotriazole on the benzene ring as the parent nucleus, The compound has a high refractive index, which can reduce the total reflection of light inside the device, so that the light extraction efficiency of the device is greatly improved, thereby improving the luminous efficiency of the device, and the triarylamine compound has strong rigidity and good It has good thermal stability and film-forming properties, can effectively isolate water and oxygen outside the device, effectively prolong the service life of the device, and is a cover layer material with excellent performance. The triarylamine compound provided by the present invention is used as a cover layer in organic light-emitting devices. Organic light-emitting devices have good luminous efficiency and long lifetime performance. |
