To expand the existing application conditions of photochromic polymers and enhance the tolerance of photochromic polymer electronic devices in extreme environments, a diamine monomer DTEDA bearing the diarylethylene (DTE) moiety was synthesized and polymerized with commercially available dihydrides to afford three polyimides (PIs, named DTEODPI, DTE6FPI and DTEHPMPI) through chemical imidization. These PIs realized reversible photo-triggered isomerization both in solution and in film state, with solution photoluminescence “on/off” effects. Semi-aromatic DTEHPMPI showed the largest contrast of color and fastest light response due to its local excited (LE) state. This research provides a simple method to prepare photochromic polymer materials with excellent comprehensive properties.

基于含二胺的二芳基乙烯部分的功能性聚酰亚胺及其光致变色机理的研究

为了扩大光致变色聚合物的现有应用条件并增强光致变色聚合物电子器件在极端环境下的耐受性，合成了带有二芳基乙烯（DTE）部分的二胺单体DTEDA，并与市售二酐进行聚合，以提供三种聚酰亚胺（PI），称为DTEODPI，DTE6FPI和DTEHPMPI）。这些PI在溶液和薄膜状态下均实现了可逆的光引发异构化，并具有溶液光致发光的“开/关”效应。半芳族DTEHPMPI由于其局部激发（LE）状态，显示出最大的色彩对比度和最快的光响应。该研究提供了一种制备具有优异综合性能的光致变色聚合物材料的简单方法。
