采用后偶氮偶联反应合成了一系列偶氮苯生色团功能化聚电解质。以1，4-环己烷二甲醇二缩水甘油醚（CH）和苯胺（AN）为原料，合成了环氧基前驱体聚合物（CH-AN）。为了比较的目的，由双酚A（BP）和苯胺（AN）的二缩水甘油醚制备另一种环氧基前体聚合物（BP-AN）。这些前体聚合物然后通过偶氮偶联反应后官能化以形成含有供体-受体型偶氮发色团的聚合物。偶氮发色团被设计成含有可电离基团以赋予聚合物自组装和光处理能力。本文报道了新合成的聚合物的结构和性能。CH-AN基偶氮聚合物具有典型的聚电解质性质。含4-（4-（羧酸）苯偶氮）苯胺发色团的聚合物可直接光刻形成大面积的表面浮雕光栅。
A series of azobenzene chromophore-functionalized polyelectrolytes have been synthesized by a post-azo-coupling reaction. An epoxy-based precursor polymer (CH-AN) was synthesized by the reaction of 1,4-cyclohexanedimethanol diglycidyl ether (CH) with aniline (AN). For comparison purposes, another epoxy-based precursor polymer (BP-AN) was prepared from the diglycidyl ether of bisphenol A (BP) and aniline (AN). These precursor polymers were then postfunctionalized by an azo-coupling reaction to form polymers containing donor−acceptor type azo chromophores. The azo chromophores were designed to contain ionizable groups to impart self-assembling and photoprocessing capabilities to the polymers. The structure and properties of the newly synthesized polymers are reported in this paper. CH-AN-based azo polymers exhibit typical properties of polyelectrolytes. The polymers containing 4-(4-(carboxylic acid)phenylazo)aniline chromophores can be directly photofabricated to form surface relief gratings with large surf...
