Title:
A-D-A TYPE ORGANIC COMPOUND AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/055196
Kind Code:
A1
Abstract:
The present invention relates to an acceptor-donor-acceptor (A-D-A) type organic compound and a preparation method therefor. The material has a thermal activation delayed fluorescence property; a monomolecular structure presents a face-to-face A-D-A arrangement in space; a main function of such compound is to realize intramolecular interaction by means of spatial non-conjugate connection; and dual-space interaction enables such material to have excellent light-emitting performance, and can be used as a material, especially a light-emitting material and/or a sensitizer, of an organic material layer of an organic light-emitting device.
