Abstract
The structures and properties of electroactive coatings based on fullerene and pyridyl-substituted fullerenopyrrolidines were studied using cyclic voltammetry, optical spectroscopy, atomic force microscopy, and other methods. The surface of the electrode of the ITO conducting glass (alloy of indium and tin oxides) was modified by direct casting or the introduction of an electroactive substance into a tetra(n-octyl)ammonium bromide matrix. Changes in the absorption spectra of the coatings agree with the presence of an electronic interaction between adjacent fullerene molecules. Tetra(n-octyl)ammonium bromide is involved in the organization of the fullerene-containing coatings with retention of the layered structure. According to the data of atomic force microscopy, the coating surface depends on both the composition of the solution and preparation method and the nature of addends in a C60 molecule. The dispersion of fullerene in the tetra(n-octyl)ammonium bromide matrix and its interaction with the alkyl groups of the latter provide the hydrophobic microenvironment necessary for reversible electrochemical processes in an aqueous solution to occur.
