G. Barbarella et al., SYNTHESIS, CHARACTERIZATION AND ELECTROCHEMICAL POLYMERIZATION OF OLIGOMETHYLTHIOPHENES, Phosphorus, sulfur and silicon and the related elements, 74(1-4), 1993, pp. 471-472
Regiospecifically methyl substituted alpha-conjugated thiophene oligom
ers have been synthesized and their structural and conformational prop
erties investigated by C-13 NMR, X-ray and force field MMP2 calculatio
ns. The use of these molecules as 'monomers' for electropolymerization
affords poly(3-methylthiophenes) showing spectroelectrochemical prope
rties which depend on the size and the substitution pattern of the sta
rting oligomer.
