The structure of stable polyfurane films doped with perchlorate anions (PFu/ClO 4 ), electrogenerated at constant deposition overpotential, has been studied by FTIR spectroscopy. Electropolymerization overpotential, and monomer/electrolyte concentration ratio were the variables analyzed in this study as a mean of determining the synthesis conditions that would best produce more aromatic polymers (which would imply a larger extended π‐conjugated system). The spectra revealed a clear influence of both variables on the films generated, and although ring opening was detected, justified by the existence of aliphatic CH, OH, and CO stretching vibrations, the spectra of these electroactive films showed higher aromaticity than had been previously reported by others authors. To study the aromaticity level and ring rupture of the PFu/ClO 4 films, the experimental profile of the 1829–1345 cm −1 FTIR region was fitted to theoretical function, and the resulting three bands were assigned and analyzed as a function of the synthesis conditions. © 2000 John Wiley & Sons, Inc.
