Description

technical field [0001] The invention relates to a conjugated polymer containing triarylamine and fluorene units and its preparation method and application Background technique [0002] With the development of science and technology, human beings have higher and higher requirements for materials. Pure electrochromic materials are increasingly unable to fully meet the growing needs. People expect electrochromic materials to have more functions, such as electroluminescent properties, resistive memory, sensor functions, etc. to achieve the goal of device integration. Since triarylamine has a unique conjugated structure and a very special electron-donating property, it can easily form amine positive ion radicals under the action of an electric field and has a high hole mobility, so it is an excellent electrotropic Color changing material. However, most of the reported electrochromic materials based on triarylamines are mostly connected with three benzene rings at the center of ...
