For the synthesis of water-soluble azo-containing polyelectrolytes, a new type of water-soluble azo compound was synthesized by introducing a carboxyl group into azo compounds by diazotization coupling reaction. Its structure was confirmed by1H-NMR, IR and UV-Vis. As the p H value changes, the absorption intensity and the peak position in the UV-Vis spectrum of the polyelectrolyte aqueous solution obtained after the polymerization of the compound all change remarkably, and the p H value sensitivity is shown. The polyelectrolyte has both good photoresponsiveness and self-assembly. Broaden the range of applications of azo-containing polymers
