[poly(4a), poly(4b)], which are the first examples of highly polar group-carrying poly(diphenylacetylenes). Poly(3a) and poly(3b) dissolved in nonpolar solvents such as toluene and chloroform, while poly(4a) and poly(4b) were insoluble in these solvents. According to TGA in air, poly(3a) and poly(3b) were thermally fairly stable among substituted polyacetylenes, and poly(4a) and poly(4b) displayed even higher
