Abstract
The rate constant of electron transfer reaction between ferrous ion in aqueous phase and decamethyferrocene located on the adjacent aqueous phase was measured by thin layer method, a simple protocol reported recently for studying electron transfer reaction at liquid/liquid interface. Despite this large increase in overall driving force, the rate constants decrease by less than an order of magnitude compared the two reaction systems of Fe3+-DMFe and Fe(CN)63−-DMFe. The results demonstrate that reorganization energy may be a dominating factor on the rate of electron transfer across the interface due to the effect of the size and symmetry of reactants in aqueous. In addition, the effect of thickness of the thin layers is investigated further.
