摘要:Disclosed are a method for preparing a series of carbazole derivatives and use thereof in organic light-emitting diodes. The structure of the material is as shown in Formula I. An organic electroluminescent device prepared by the material can have a significantly improved power efficiency and an external quantum efficiency for the device and an extended life for an orange light or red light device; moreover, the material has characteristics, for example, methods for the synthesis and purification of the material are simple and suitable for large-scale production, and is an ideal choice as a luminescent material for organic electroluminescent devices. The use of the organic electroluminescent diode material as a carrier transport material or as a luminescent material alone or as a host material in a light-emitting layer also falls within the scope of protection.

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.
