Title:
FLUORESCENT MATERIAL AND ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/262063
Kind Code:
A1
Abstract:
Embodiments of the present application provide a fluorescent material. The fluorescent material has a molecular structure combining an electron donor and an electron acceptor. On the basis of a structure of combined triphenylborane and triphenylamine, a fluorescent material having a low singlet-triplet energy gap, high luminous efficiency, and a fast reverse intersystem crossing constant is obtained by means of controlling structures of different electron-donating units so as to adjust charge transport strength and change the electron-donating capability of the whole, thereby obtaining an electroluminescent device having high luminous efficiency.
