The films of an amphiphilic C 60 ‐EDTA (C 60 EA) and its tetramethyl ester (C 60 EM), prepared both by drop‐coating and Langmuir‐Blodgett (LB) technique, were studied by cyclic voltammetry in acetonitrile solutions of tetra‐ n ‐butylammonium hexafluorophosphate as the supporting electrolyte. The drop‐coated film of C 60 EM displayed four pairs of redox peaks, which vanished after a few cycles due to the film dissolution. For the LB film of C 60 EM, three irreversible reduction peaks were observed. Both the drop‐coated and the LB film of C 60 EA showed two irreversible reduction peaks.
