摘要:The present invention relates to a chiral thermally activated delayed fluorescence (TADF) material and a preparation method therefor. The chiral TADF material is R/S-18,21-bis(10H-phenoxazine-10-yl)-3,4,5,6,7,8,9,10-octahydrodibenz[a,c]dinaphtho[2',1':5,6;1',2':7,8][1,4]dioxin[2,3-i]phenazine or R/S-16,17-bis(4-(10H-phenoxazine-10-yl)phenyl)-3,4,5,6,7,8,9,10-octahydrodinaphtho[2',1':5,6;1',2':7,8][1,4]dioxane[2,3-g]quinoxaline. The provided compound has the characteristics of rigid large-plane twisted structure and significant intramolecular charge transfer (ICT) effect, and has the typical advantages such as TADF property, circular polarization (CPL) property, high photoluminescence quantum yield (PLQY), and good thermal stability. Moreover, the chiral TADF material has few synthesis and preparation steps, readily available raw materials, simple synthesis and purification processes, and high yield, and can be synthesized and prepared on a large scale.
