ABSTRACT
Films of polythiophene (PT), poly(3-metylthiophene) (PMT), poly(3-hexylthiophene) (PHT), and poly(3-octylthiophene) (POT) were electropolymerized on ITO-covered glass anodes under an applied voltage of 8V v.s. an Ag/AgCl reference electrode. Uniaxial stretching of polythiophene prepared in this way has previously been reported [1,2]. The films were electrochemically reversed, and further reduced by boiling in methanol to give deep red, flexible films with fairly smooth surfaces. The smoothness decreases with increasing length of the substitutents, and increasing film thickness. Films of PHT and POT are partially soluble in CHCl3.
