Abstract

This article demonstrates that new redox active films can be electrochemically generated by reduction of a chemically modified fullerene (the ferrocene−fullerene conjugate 2‘-ferrocenylpyrrolidino-[3‘,4‘;1,2][C60]fullerene, Fc-C60) and [Pd(ac)2]3. These films are electrochemically active in both positive and negative potential regions. The formation and electrochemical properties of this Fc-C60/Pd film have been studied using cyclic voltammetry and electrochemical quartz crystal microbalance techniques. The surface morphology and infrared spectra of the film are also reported. At negative potentials, the electrochemical behavior of the new Fc-C60/Pd film shows features similar to the ones displayed for the previously studied C60/Pd film. In the positive potential range, peaks related to charge-transfer processes of the ferrocene units linked to the polymer backbone are observed. Reduction of the film at negative potentials is accompanied by transfer of cations at the solution/film interface and their tran...
