HYDROPHOBIC FERROCENE DERIVATIVES AS POTENTIAL STANDARDS IN ELECTROCHEMISTRY

Ferrocene (FcH) derivatives monosubstituted by palmitoyl (1), hexadecy l (2), 1-adamantoyl (3) or 1-adamantylmethyl (4) groups were sythesize d and characterized by NMR, mass and Fe-57 Mossbauer spectroscopy, The structure of 1-adamantoylferrocene was determined by single-crystal X -ray diffraction. Cyclic voltammetry on gold and glass-like carbon ele ctrodes demonstrated that the compounds can serve as electrochemical s tandards for special cases since their ferrocene/ferricinium redox pot ential remains stable and reversible, while the properties such as sol ubility, diffusion coefficients and surface tension are strongly solve nt-dependent.
