THERMALLY ACTIVATED DELAYED FLUORESCENCE DARK RED LIGHT MACROMOLECULAR MATERIAL AND PREPARATION METHOD THEREFOR

摘要

Provided in the present invention is a thermally activated delayed fluorescence (TADF) dark red light macromolecular material. A main chain is used for polymerizing a TADF molecular structure, and a side chain is connected to an alkyl chain, and the TADF macromolecular material with such structure has excellent TADF characteristics and dissolvability. Furthermore, the material to which the present invention relates may be used for preparation of electroluminescent devices by means of solution processing and may achieve good device effects.
