Title:
BLUE LIGHT THERMALLY ACTIVATED DELAYED FLUORESCENCE MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/098146
Kind Code:
A1
Abstract:
The present invention provides a blue light thermally activated delayed fluorescence (TADF) material and use thereof. With regard to the blue light TADF material involved therein, an electron acceptor structure having strong rigidity is selected to improve the thermal stability of the molecule, and three blue light TADF materials having high luminescent properties are designed and synthesized by selecting the combination of different raw material-derived functional groups. Further, electroluminescent devices using the blue light TADF material involved in the present invention as a luminescent material all achieve high luminance and good device effects.
