Abstract

Effect of addends in fullerene compounds on the fullerenes' redox behavior in the matrix of tet-raoctylammonium bromide, an artificial cationic lipid, deposited on conducting glass is studied by example of di- and trisubstituted fullerenopyrrolidines and a methanofullerene derivative. It is shown by cyclic voltammetry that in all cases the hydrophobic interaction of fullerenes with alkyl radicals in the matrix, as well as electrostatic interaction of the fullerene reduction products (anions), shifts the fullerene reduction potentials toward positive values. This allows performing quasireversible redox-transformation in neutral aqueous media. It is shown that the rate of electron transfer to and from fullerene in the fullerenopyrrolidines is higher than in methanofullerene, which presumably can be explained by violation of the symmetry and conjugation partial lack due to the introducing of the methane fragment.
