Thin fullerene films of controlled roughness were electrophoretically deposited from C60 suspensions formed in mixed toluene-ethanol solutions. Mass of the deposited films, determined by piezoelectric microgravimetry (PM) with the use of an electrochemical quartz crystal microbalance, exponentially increased with time. Size of the AFM imaged C60 grains in the films depended both on time of C60 aggregation in bulk solution prior to deposition and strength of the electric field applied. In the accessible potential range, cyclic voltammetry (CV) curves for the films in 0.1 M (TBA)PF6, in acetonitrile, featured four main cathodic peaks formed during the negative potential excursion. These peaks corresponded to four one-electron reductions. Simultaneously recorded PM and CV curves showed an overall mass decrease, corresponding to stepwise C60 electroreduction and the complete dissolution of the C{sub 60}{sup 3-} film. The CV, XPS and XRD analyses indicated the film swelling and reversible ingress of both TBA+ counter- and PF{sub 6}{sup -} co-ion into the C{sub 60}{sup -} film.
