Abstract

A multifunctional triarylamine-based polyamide containing a fused-ring naphthyl side group structure and its preparation method and application. The present invention relates to a multifunctional triarylamine-based polyamide containing a fused-ring naphthyl side group structure and a preparation method thereof and apply. The purpose of the present invention is to solve the problems of poor solubility, poor heat resistance and single function of the existing triarylamine-based polyamides. In the present invention, p-bromoaniline is used as a raw material to undergo nitration reaction with p-fluoronitrobenzene, and then undergo condensation reaction with 1-naphthylboronic acid, and then dinitro groups are reduced to diamine groups. The diamine groups are condensed with different diacids to form polyamides. The polymer of the invention has excellent electrochromic performance and AIE effect, and the invention is applied in the field of electrochromic polymers.

Description

technical field [0001] The invention relates to a multifunctional triarylamino polyamide containing a condensed ring naphthyl 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 pres...
