Abstract:
An acridine derivative including a structure of formula (I) is provided. The acridine derivative can be used as a fluorescent material, in particular, it is included in an organic light-emitting layer as a dark blue thermally-activated delayed fluorescent material, thereby a series of high-performance electrothermally activated delayed fluorescent devices are produced.
