Patent ID: 11725003

Abstract:
The present disclosure discloses an amine derivative and an organic electroluminescent device thereof, and relates to a technical field of organic photoelectric materials. The technical problem to be solved by the present disclosure is that the current light extraction material has poor thermal stability and the organic electroluminescent device has short service life. The amine derivative of the present disclosure is a diamine with a bridging group containing a fluorenyl group or a spirofluorenyl group, and the substituent group on N contains at least one benzoxazolyl group, benzothiazolyl group or benzimidazolyl group. The organic electroluminescent device of the present disclosure comprises an anode, an organic layer, a cathode and a light extraction layer, the organic layer is located between the anode and the cathode, and the light extraction layer comprises the amine derivative of Formula I according to the present disclosure.
