The synthesis of main chain diarylethene homopolymer using new convenient polymerization method based on Friedel-Crafts alkylation and its photochromic properties, was analyzed. The new polymerization method is very efficient to produce the polymers of various molecular weight in high yield. The polymer exhibits the characteristics photochromic property as the corresponding monomeric unit in solution and also in solid film. The fatigue resistance of the polymer to UV light was significantly improved compared with monomer unit. This polymerization of photochromic diarylethene using Friedel-crafts alkylation could be widely applied in the polymerization of many functional aromatic compound as evidently shown by dimerization of a benzothiopene derivative.
