Title:
ORGANIC ELECTROLUMINESCENT MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/197739
Kind Code:
A1
Abstract:
Disclosed is an organic electroluminescent material, the molecular general formula thereof being Da-π-Ac, wherein Da is an aggregation-induced luminescent group, π is a conjugated bond and Ac is a strong electron-withdrawing group. The preparation method for the organic electroluminescent material of the present invention is simple, the yield is relatively high and the thermodynamic stability is good; and the organic electroluminescent material can cover a visible light region, has a good electroluminescent effect and can prepare a non-doped type organic electroluminescent device.
