The invention discloses a benzidine compound and an organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. This kind of compound connects substituted or unsubstituted phenanthrenecarbazolyl groups on the main structure of aromatic amines. The preparation method is simple, the raw materials are easy to obtain, and it has good thermal and chemical stability, and has good hole transmission capacity. This type of compound is used as a hole transport layer in an OLED device, which can significantly improve the luminous efficiency of the device, and at the same time effectively reduce the driving voltage of the device, which solves the problems of low luminous efficiency and high driving voltage in the prior art. It is a kind of OLED material with excellent performance. |
