A SYSTEMATIC SPECTROELECTROCHEMICAL INVESTIGATION OF ALKYL-SUBSTITUTED ANILINES AND THEIR POLYMERS

Various aniline derivatives carrying one or two alkyl substituents in Various positions (alkylanilines, toluidines and xylidines) were polym erized electrochemically. The obtained conducting polymers were charac terized by cyclic voltammetry, in situ infrared spectroscopy and in si tu conductivity measurements. Differences in the electrochemical prope rties of the investigated monomers and polymers are explained an the b asis of steric and electronic effects of the substituents. These concl usions are supported by data of vibrational spectroscopy.
