Title:
THERMALLY ACTIVATED DELAYED FLUORESCENCE MONOMOLECULAR WHITE LIGHT MATERIAL AND SYNTHESIZING METHOD THEREFOR, AND ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/082656
Kind Code:
A1
Abstract:
The prevent invention provides a macromolecule Thermally Activated Delayed Fluorescence (TADF) material, and further provides a TADF monomolecular white light material, which is synthesized from raw materials of first groups and second groups, and 3,3'-dibromo-1,5,1',5'-tetramethyl-1,2,4,5-tetrahydrazine. The synthesizing method for the TADF monomolecular white light material comprises: a step of preparation of a first mixed solution, a first extraction step, a step of preparation of a second mixed solution, and a second extraction step. An organic electroluminescent device, comprising a TADF monomolecular white light material light-emitting layer.
