| Abstract: | Abstract Regiospecifically methyl substituted α-conjugated thiophene oligomers have been synthesized and their structural and conformational properties investigated by 13C NMR, X-ray and force field MMP2 calculations. The use of these molecules as ‘monomers’ for electropolymerization affords poly(3-methylthiophenes) showing spectroelectrochemical properties which depend on the size and the substitution pattern of the starting oligorners. |
