Title:
HIGH-EFFICIENCY BLUE LIGHT OLED MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/221249
Kind Code:
A1
Abstract:
A high-efficiency blue light OLED material, a preparation method therefor and an application thereof. The chemical formula of the blue light OLED material is [(Hdma)K(H2ettc)]n, Hdma being dimethylamine cation, and H2ettc being semi-deprotonated tetrakis[4-(4'-carboxyphenyl)]tetraphenylethylene; the blue light OLED material has relatively high-purity blue fluorescence emission performance and relatively high quantum yield. Compared with current commercialized blue light phosphors, the blue light OLED material has a relatively fast response speed and pure color performance; in addition, it overcomes disadvantages such as costly precious metal doping, and has application value in the field of green synthesis of high-efficiency blue light OLED materials.
