Abstract:
The present disclosure provides an electroluminescent material, a method for manufacturing the electroluminescent material, and a luminescent device, by employing a fluorenyl group showing good planarity and strong visible π-π* absorption as π-based system, and simultaneously introducing a compound containing a carbazole group as an electron donor and a compound containing aniline as an electron acceptor to realize an electroluminescent material, a method for manufacturing the electroluminescent material and a luminescent device with emitting a blue light and a high electroluminescence efficiency.
