A simple and efficient method is presented for preparation of insoluble thin films of C{sub 60} and the (TBA{sup +})(C{sub 60}{sup {minus}}) and (TBA{sup +}){sub 2}(C{sub 60}{sup 2{minus}}) salts where TBA{sup +} represents the tetra-n-butylammonium cation. The method consists of bulk electroreducing a fine suspension of solid C{sub 60} in acetonitrile solutions under a controlled potential which is sufficiently negative to generate the soluble C{sub 60}{sup 3{minus}} anion, followed by electrooxidative deposition of a neutral C{sub 60} film on the surface of a gold/quartz crystal working electrode. The properties of the electrodeposited films were examined by simultaneous cyclic voltammetry and electrochemical quartz crystal microbalance experiments which enabled determination of the stoichiometry and mass of the film. 11 refs., 21 figs.
