COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/076198
Kind Code:
A1
Abstract:
A fluorescent dye compound. The mother nucleus group of the compound is a fused aromatic hydrocarbon group with a triplet energy level T1 of less than 2.2 eV, the substituent group at the periphery of the mother nucleus is a large sterically hindered group with a triplet level T1 of greater than 2.2 eV, and the molecular excitation state first triplet energy level of the compound is distributed in the mother nucleus group moiety. The compound is applied to an organic electroluminescent device as a luminescent material to improve luminous efficiency.
