- Abstract
- The effects of N- and C-methyl substitution on electrical and spectral properties of pyrrole,
2,2¢-bipyrrole, and the corresponding polymers were investigated. The whole series of
monomethyl and N- or Câ-dimethyl-substituted 2,2¢-bipyrroles was synthesized, and the
electrochemical and spectral properties of all the compounds were investigated under
identical testing conditions. The corresponding polymers were prepared by electrochemical
anodic oxidation under comparable experimental conditions and their spectroscopic and
conductivity properties evaluated for comparison. The higher degree of efficiency in
transmission of electronic effects associated with methyl substitution at Câ with respect to
substitution at N was clearly demonstrated. The influence of the symmetry of the starting
monomer (C2v or Cs) on the electrical properties of the resulting polymers is discussed. (literal)
