ELECTROPOLYMERIZATION OF ANILINE AND DITHIENOTHIOPHENE AT ROTATING RING-DISC ELECTRODE

Electropolymerization of aniline acid 3,4-b:3',4'-d:dithienothiophene (DTT) at rotating ring-disc electrode was studied. Strong influence of electrode rotation on thickness of polymeric film was observed for an iline but not for DTT. Reduction waves of intermediate products at the ring electrode revealled a two-step or one-step reaction for aniline and DTT, respectively. Mechanisms of electropolymerization of the comp ounds were discussed suggesting the route via cation radicals and olig omers for DTT and a more complicated path for aniline.
