Abstract
(EN)
Provided are an electroluminescent material, a manufacturing method for the electroluminescent material, and a light emitting device. A fluorenyl group having good planarity and strong visible π-π* absorption is selected as a π-based system, and a compound comprising a carbazole group is introduced as an electron donor and a compound comprising aniline is introduced as an electron acceptor, thereby realizing the electroluminescent material that can emit blue light and has high electroluminescence efficiency, the manufacturing method for the electroluminescent material, and the light emitting device.
