Title:
SYNTHESIS AND PHOTOELECTRIC PROPERTY RESEARCH OF CARBAZOLE ROOM-TEMPERATURE PHOSPHORESCENT MATERIAL CONTAINING S/SE/TE HEAVY ATOMS
Document Type and Number:
WIPO Patent Application WO/2021/068511
Kind Code:
A1
Abstract:
Disclosed is a preparation method of D-A type carbazolyl derivatives and luminescent properties thereof. The carbazolyl derivatives have a structural general formula represented by formula (I). The D-A type structure comprises carbazole as a donor unit and benzoyl as an acceptor unit. Three related materials have excellent solubility and thermal stability. The preparation method of carbazolyl derivatives in the present invention mainly employs a Stille coupling reaction of 4-iodobenzoyl and a five-membered heterocycle mono-substituted with a tin compound. The preparation method provided by the invention has a simple route, few steps, and low production cost. More importantly, by substituting heteroatoms of different weights, the luminescent properties of the materials can be tuned and transition from fluorescence to phosphorescence achieved. The invention has broad application prospects in the fields of organic light-emitting diodes and biological imaging.
