ABSTRACT WITHDRAWN

It is widely accepted that the identity of the anion dopant in electrodeposited conducting polymer films impacts the electrical properties of the resulting polymer. We focus here on the effect of size, charge, and pi-pi interactions on films based on 3-methylthiophene and 3,4-ethylenedioxythiophene. Results of characterization of the films based on cyclic voltammetry, electrochemical impedance spectroscopy, Raman spectroscopy, scanning electron microscopy, and grazing angle x-ray powder diffraction will be used to provide insight into trends in conjugation length of the polymer and its crystallinity as well as charge transport through the film.
