The anodic copolymerization of pyrrole and N‐(ω‐ferrocenylalkyl)pyrroles, FcPy‐n, at platinum electrodes in an electrolyte consisting of tributylammonium benzenesulfonate in moist acetonitrile is optimized with respect to the absolute and relative concentrations of the monomers and the spacer length of FcPy‐n. The copolymer composition is estimated from cyclic voltammograms of the polymer films. Only films with less than 20% FcPy‐n content show the typical polypyrrole voltammograms. Free standing copolymer films with a conductivity of ca. 10 S cm −1 can be prepared.
