Abstract

The invention discloses a triarylated amine and fluorene unit containing conjugated polymer as well as a preparation method and an application of the triarylated amine and fluorene unit containing conjugated polymer, relates to the triarylated amine and fluorene unit containing conjugated polymer and the preparation method and the application of the triarylated amine and fluorene unit containing conjugated polymer, and solves the technical problem of single performance of the conventional electrochromic material. The structural formula of the triarylated amine and fluorene unit containing conjugated polymer is shown in the description, wherein n is a positive integer. The preparation method of the triarylated amine and fluorene unit containing conjugated polymer is as follows: 1, synthesizing a triarylated amine monomer; 2, carrying out the suzuki reaction. The triarylated amine and fluorene unit containing conjugated polymer is applied to serving as the electrochromic material, electroluminescent material, the resistive memory material or the sensor functional material. The application range of the electrochromic material is expanded, an established fluorene-triarylated amine system fully combines the advantages of the triarylated amine and a fluorene unit and overcomes the defects of the triarylated amine and the fluorene unit, and the hole transfer capability is stronger, and the emission efficiency of a device is enhanced.

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 ...
