Abstract

A triarylamino polyamide containing a fused ring anthracene side group structure and its preparation method and application. The invention relates to a triarylamine polyamide containing a fused ring anthracenyl side group structure and its preparation method and application. The purpose of the invention is to solve the problems of poor heat resistance and poor film adhesion of electrochromic polymer films in the existing triarylamine-based polyamides. In the present invention, p-bromoaniline is used as a raw material to undergo nitration reaction with p-fluoronitrobenzene to carry out condensation reaction with 9-anthracenylboronic acid, and then the dinitro group is reduced to diamine group. The diamine groups are condensed with different diacids to form polyamides. The polymer of the invention has excellent electrochromic performance and good stability. The invention applies to the field of electrochromic polymers.

Description

technical field [0001] The invention relates to a triarylamino-based polyamide containing a fused ring anthracene side group structure, a preparation method and application thereof. Background technique [0002] Electrochromic polymers are polymers that change color when the voltage or current is changed. Conductive polymers such as polythiophene, polypyrrole, polyacetylene, and some liquid crystal polymers can be used as electrochromic materials. The conductive polymer itself is a delocalized conjugated structure, and the energy gap between the valence band and the conduction is very small. If the polymer is doped (an ionic compound of an electron donor or acceptor), the energy band structure will also follow. Changes occur, and by applying an external electric field, the absorption of light is further changed, resulting in a change in color. As an emerging functional polymer material, electrochromic polymers have broad application prospects. [0003] At present, electro...
