以可再生单体3-氨基-4-羟基苯甲酸（3，4-AHBA）为单体，通过电聚合法合成了可溶性π共轭聚合物。与聚苯胺相比，该聚合物在普通溶剂中具有更高的溶解度，这是由于极性侧基如羧基和羟基。该聚合物显示出基于侧基的溶剂化和电离的各种变色行为，并给出具有与半导体一样高的导电率的柔性膜。
Soluble pi-conjugated polymer derived from a renewable monomer, 3-amino-4-hydroxybenzoic acid (3,4-AHBA), was synthesized by an electropolymerization. The polymer has higher solubility in common solvents, compared to polyaniline, due to the polar side groups such as carboxyl and hydroxyl. The polymer showed various chromic behaviors based on the solvation and ionization of the side groups, and gave a flexible film with a conductivity as high as that of semiconductor.
