Abstract
The preparation and characterization of electroactive, dendrimer-containing films is discussed. Polymer films were prepared by electropolymerization of a thiophene-functionalized poly(amidoamine) dendrimer (G4Th) and by electrocopolymerization of G4Th and poly(3-methylthiophene) (P3MeTh). The composite P3MeTh/G4Th film was found to consist of up to 80% of the dendrimer. Control experiments indicated that dendrimers not functionalized on their periphery with thiophene groups are not incorporated into the P3MeTh matrix. The conductivity of the composite films was the same as that of the P3MeTh-only films, although UV−vis spectroscopy indicated reduced conjugation in the composite. The dendrimer-containing films were found to sorb Pt2+ ions.
