摘要：

Various derivatives of polybithiophene were synthesized and characterized. Poly(3,3'-dibutoxy-2,2'-bithiophene) and poly(4,4'-dibutoxy-2,2'-bithiophene) were found to be conducting upon doping but only partially soluble in common organic solvents. The oxidation potential of poly(4,4'-dibutoxy-2,2'-bithiophene) was only +0.05 V vs SCE, one of the lowest values for a polythiophene derivative. This low oxidation potential allows then the formation of a stable conducting state in the polymer. Moreover, upon oxidation, thin films of poly(dialkoxybithiophenes) became nearly transparent. Asymmetric disubstitution gave poly(3-butoxy-3'-decyl-2,2'-bithiophene) and poly(4-butoxy-4'-decyl-2,2'-bithiophene) which were completely soluble in chloroform. Their properties were intermediate between those of poly(alkylthiophenes) and poly-(dialkoxybithiophenes).
