Abstract

The electrochemical polymerization of the monomer 3,3’’-di[(S)-(+)-2-methylbutyl]-2,2’:5’,2’’-terthiophene (DMBTT) was carried out potentiodinamically on indium tin oxide (ITO), Pt or glassy carbon (GC) electrodes in anhydrous CH3CN with TBAPF6 as supporting electrolyte. The films of poly(DMBTT) were characterized by various analytical techniques including UV-Vis-NIR absorption spectroscopy, cyclic voltammetry (CV), scanning electron microscopy (SEM), and gel permeation chromatography (GPC). The most outstanding properties of the polymer electrochemically synthesized were compared with those of the same polymer obtained by a chemical method. The major difference lay in the length of the polymeric chain, which resulted much shorter for the electrochemically generated product. The film obtained on ITO displayed a reversible electrochromic behavior under potential switching between -0.50 and +1.00 V vs. SCE.
