A novel series of functionalized polythiophenes incorporating 3-(omega-bromoalkyl) pendants are synthesized by electrochemical polymerization. The effect of the solvent on the electrosynthesis is investigated. The polymeric films are characterized using cyclic voltammetry, Fr-IR, AFM and SEM microscopy. The poly [3-(6-bromohexyl)thiophene] film cast on GC or ITO electrode surface is compared with a sample obtained by a chemical method. (c) 2006 Elsevier Ltd. All rights reserved.
