Thermally activated delayed fluorescent material, method of fabricating same, and electroluminescent device

摘要

A thermally activated delayed fluorescent material, a method of fabricating the same, and an electroluminescent device are provided. An electron donor and an electron acceptor of the thermally activated delayed fluorescent material are connected with each other by a hexatomic ring. Thus, luminous efficiency of the thermally activated delayed fluorescent material can be improved.
