Abstract

The invention discloses triptycene-centered methoxytriphenylamine-containing polyamide as well as a preparation method and the application thereof, and relates to triptycene-centered methoxytriphenylamine-containing polyamide as well as a preparation method and the application thereof. In order to solve the problems of low solubility, no electrochromism performance and narrow application range of triptycene caused by overlarge rigidity of triptycene in an organic solvent, the invention provides a triptycene-centered methoxytriphenylamine-containing polymer as well as a preparation method and the application thereof in electrochromism. According to the invention, triiodo-triptycene is used as a raw material and is subjected to a substitution reaction with 4-methoxy-4 '-nitrodiphenylamine to generate a triptycene-centered methoxy-containing triphenylamine monomer. A diacid monomer is reacted with a triptycene-centered methoxyl-containing triphenylamine monomer to generate the triptycene-centered methoxyl-containing triphenylamine polymer. The method is applied to the field of electrochromism.

Description

technical field [0001] The invention relates to a triptycene-centered polyamide containing methoxy triphenylamine and its preparation method and application. Background technique [0002] Triptycene has a special three-dimensional rigid structure and easy functionalization characteristics, and the isolation effect of triptycene structure can effectively prevent the accumulation of polymer main chains and the formation of excimer associations, which has attracted researchers. Interest in applying it to the field of optoelectronic materials. However, triarylamine (TAA)-based polymers, which are constructed by linking triptycene groups with triphenylamine groups, are not enough as optoelectronic materials due to their limited solubility. Therefore, the triarylamine (TAA)-based polymers constructed by connecting triptycene groups with triphenylamine groups have been rarely studied in the field of electrochromism, and their applications in the fields of photoelectric detection a...
