Title:
ORGANIC ROOM-TEMPERATURE ELECTROPHOSPHORESCENT MATERIAL, AND PREPARATION METHOD THEREFOR AND ORGANIC ELECTROLUMINESCENT DIODE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/098740
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of photoelectric materials, and particularly relates to an organic room-temperature electrophosphorescent material, and a preparation method therefor and an organic electroluminescent diode thereof. The organic room-temperature electrophosphorescent material provided in the present invention has the characteristic structure of a fused arylamine electron donor D and an electron acceptor A, wherein the fused arylamine electron donor D has a structure of formula II-1 or II-2, and the fused arylamine electron donor provides molecular rigidity to inhibit the non-radiative attenuation of triplet-state excitons; X regulates and controls the intramolecular charge transfer while enhancing the spin-orbit coupling effect; A, serving as an electron acceptor, receives electrons provided by D; and finally, an effective room-temperature phosphorescence is obtained in an amorphous state.
