Title:
ORGANIC LIGHT-EMITTING MATERIAL AND PREPARATION METHOD THEREFOR, AND ORGANIC LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/232852
Kind Code:
A1
Abstract:
Disclosed in the present invention are an organic light-emitting material and a preparation method therefor, and an organic light-emitting device. The organic light-emitting material comprises a benzophenanthrene derivative which has good planarity and strong visible π-π* absorbing ability and has high-quantum yield fluorescence emission capability. Therefore, the benzophenanthrene derivative with a large π-conjugated system has an efficient electron transmission characteristic, and as an efficient electron-withdrawing group, the benzophenanthrene derivative improves the charge transfer efficiency and effectively improves the light-emitting efficiency of the organic light-emitting device.
