Determination of Formal Rate Constant for n-alkyl-ferrocene Drivatives by Fast Scan Cyclic Voltammetry

Abstract

Formal rate constants for electrode reactions of n-alkyl-ferrocene derivatives in propylene carbonate solution were determined by Fast Scan Cyclic Voltammetry. Simple correction for voltammograms was done by the subtraction of blank voltammogram from the original voltammogram to reduce the effect of the double layer charging current. The formal rate constant decreased from 7.29 ± 0.86 (ferrocene) to 0.0261 ± 0.0062 cm s⁻¹ (n-tetradecylferrocene) with increasing alkyl chain length of ferrocene derivatives.
