Abstract

Polythiophene-based polyelectrolyte multilayers have been layer-by-layer deposited on ITO/glass and characterized by UV-vis spectroscopy, cyclic voltammetry and conductivity. Multilayers in which both polycation and polyanion are based on the same polythiophene backbone are reported for the first time. Uv-vis spectroscopy and cyclic voltammetry indicate a linear dependence of the amount of deposited polymer on the number of deposition cycles. The amount of deposition depends on the oxidation state of the polythiophene. The sheet and perpendicular conductivities of the multilayers and their photoluminescence properties are reported.
