Abstract

Provided are a triarylamine compound and an organic electroluminescent device thereof, which specifically relate to the field of organic electroluminescent materials. The triarylamine compound has high hole mobility, good thermal stability and great film formability, and when applied to the hole transport layer of an organic electroluminescent device, can reduce the energy potential barrier in a hole injection process, improve hole injection efficiency so that the hole transport rate is balanced with electron transport, increase the recombination probability of excitons in a light-emitting layer, and achieve the maximum recombination of carriers, thereby improving the luminescence efficiency of the device and extending the lifetime of the device. Therefore, the compound has great application and commercial values in the application of OLED devices and possesses a good industrialization prospect.
