Chloromethylation of bis(2-thienyl) sulfide is accompanied by fast polycondensation of the primary chloromethylation product with the initial sulfide. The reaction gives a new polymer in which the thiophene rings are alternately separated by sulfur atoms and methylene groups. Fusion of the polymer with molecular sulfur gave new sulfur-enriched polymers whose specific electric conductivity is comparable with that of organic semiconductors.  相似文献
