Electropolymerization of 2,5-di(-2-thienyl)-pyrrole was carried out in dichloromethane and acetonitrile on platinum. Acetonitrile was found to be the most suitable solvent for film formation. The effect of supporting electrolyte and the monomer concentration on the electropolymerization process is discussed. The surface morphology of the polymer was investigated by scanning electronic microscopy (SEM). Stable and adherent films were synthesized evidencing the critical importance of water presence during the synthesis of this kind of systems, and the relevance of controlling experimental variables affecting hardly the morphology of the film, hence, the macroscopic properties of the polymeric deposit like conductivity and doping level.
