Abstract

The invention discloses triarylamino polyamide containing a condensed ring anthryl side group structure as well as a preparation method and application of thereof, and relates to triarylamino polyamide containing a condensed ring anthryl side group structure as well as a preparation method and application thereof. The invention aims to solve the problems of poor heat resistance and poor electrochromic polymer film attaching capacity of existing triarylamine polyamide. The method comprises the following steps: taking p-bromoaniline as a raw material, carrying out nitration reaction on p-bromoaniline and p-fluoronitrobenzene, carrying out condensation reaction on a product of the nitration reaction and 9-anthraylboronic acid, and then carrying out binitro reduction to obtain diamino; and carrying out condensation reaction on the diamino and different diacids to generate polyamide. The triarylamino polyamide provided by the invention has excellent electrochromic performance and good stability, and is applied 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...
