Abstract

The invention relates to aromatic polyester containing triphenylamine and a preparation method and application of the aromatic polyester and aims to solve the problem that existing polyester is low in solubility in organic solvent and crystalize easily. The structural formula of the aromatic polyester containing triphenylamine is showed in the description and claims. The preparation method includes the steps of firstly, preparing N, N'-di(beta-naphthyl)-N, N'-di(4-carboxyl styrene) p-phenylenediamine monomer; secondly, performing polymerization reaction; thirdly, performing curing and film forming to obtain the aromatic polyester containing triphenylamine. By the preparation method, the aromatic polyester containing triphenylamine can be obtained.

Description

technical field [0001] The invention relates to an aromatic polyester and its preparation method and application. Background technique [0002] Electrochromic materials and devices have been studied for many years. Electrochromic system devices can be used for light and thermal protection of windows, mirrors, glass, maintenance systems, optical filters and display panels. Currently, electrochromic materials have two commercial applications: one is automotive rearview mirrors; the second is electrochromic smart windows. [0003] It is well known that aromatic polyesters have high thermal stability, optical transparency in the visible region and excellent mechanical properties. So far, most research has focused on their high-performance applications. The applications of these polymers as materials for photonic / electronic devices are less studied. Therefore, it is an important topic to adjust the photophysical and electrical properties of polyesters through a simple condens...
