Electrochemical dopping of tetramethylammonium ions into C60 film

[[abstract]]The electrochemical properties of C60 films were studied by cyclic voltammetry and electrochemical quartz crystal microbalance technique in organic electrolyte solution. Tetramethylammonium perchlorate was used as a supporting electrolyte in acetonitrile solution. Thin films are prepared by solvent quickly evaporated method on a preheated glassy carbon electrode. The electrochemical response of C60 films is consistent with a reduction mechanism that is dominated by ion transport to form contact ion pair. In the proposed mechanism, swelling of the film with solvent and intercalation of cations into the film proceed parallelly. The stability of the film with respect to successive redox cycles was also interpreted.[[notice]]補正完畢[[journaltype]]國
