Abstract
A thermally activated delayed fluorescent (TADF) deep-red light polymer material is provided, and includes a main chain to polymerize a TADF molecular structure, and a side chain to connect with an alkyl chain. The TADF polymer material of this structure has excellent TADF characteristics and solubility. Further, the material can be used to fabricate an electroluminescent device by a solution processing, and a good device effect can be obtained.
