Polyindole and poly(5-cyanoindole) : electrochemical and FT-IR spectroscopic comparative studies

Indole (C8NH7) and 5-cyanoindole (C9N2H6) can be electropolymerized in the presence of ClO4− anions. The electrochemical behaviour of both polymers is discussed. FT-IR studies of their doped and undoped forms agree with a 2,3 type structure of regular, statistical or random conformation
