Abstract

The invention discloses a triarylamine polymer and application thereof. The triarylamine polymer has a structural general formula shown in the following formula (I), wherein the definition of substituent groups in the formula (I) is the same as that in the specification. According to the invention, the triarylamine polymer has good stability and hole mobility, and can be used as a hole transport material to be applied to a quantum dot light-emitting device (QLED), an organic light-emitting device (OLED) and a perovskite solar cell (PSC).

Description

technical field [0001] This application relates to but not limited to the field of organic optoelectronic materials, in particular to a triarylamine polymer and its preparation method and application. Background technique [0002] Triarylamine small molecular compound is an electron-rich compound with π-conjugated structure. Its nitrogen atom easily loses electrons to form cationic radicals. Therefore, this compound has relatively good electron-donating properties and can be widely used as a hole-transporting material. In organic photoelectric devices, such as quantum dot light-emitting diodes (Quantum Dot Light Emitting Diodes, QLED), organic electroluminescent diodes (Organic Light-Emitting Diode, OLED), perovskite solar cells (Perovskite Solar Cells, PSC), etc. However, because of the relatively low glass transition temperature (T g ) and hole mobility, which limit its use in organic optoelectronic devices. [0003] In recent years, the application and research of optoe...
