摘要：

A series of 3,3'-dialkyl-2,2'-bithiophenes (DAT2s) has been synthesized by the nickel-catalyzed Kumada coupling of 2-bromo-3-alkylthiophene with 2-(3-alkylthienyl) magnesium bromide. These monomers were analyzed by NMR and UV-Vis spectroscopies. The monomers were oxidatively polymerized with iron(III) chloride to yield the respective pi-conjugated poly(3,3'-dialkyl-2,2'-bithiophene)s. The new polymers were characterized with H-1 NMR and UV-Vis spectroscopies. Conductivity was in the order of 10-10(2) S/cm, depending upon the length of the alkyl chain.
