The redox potentials of ferrocene and decamethylferrocene were determined in a number of molecular and ionic solvents and used as a probe for polarity of room temperature ionic liquids. No macroscopic solvent property is simply related to redox potentials. Single empirical solvent parameters also are not able to describe the differences in potentials. Instead, Kamlet-Taft multiparameter relationship fits well ferrocene redox potentials variation with both molecular solvents and ionic liquids, well describing specific solvent-solute interactions with both molecules.
