Kinetics of Mediated Electron Transfer Between Viologen Groups in a Self-Assembled Monolayer and Metal Complexes in Solution

Abstract

Self-assembled monolayers are used in an experimental configuration which allows the extraction of the cross reaction electron exchange rate constant for the electron transfer between a viologen group embedded within the SAM and a metal complex in solution. This cross reaction rate constant is compared with predictions from the Marcus theory using the cross reaction relation and the known self-exchange rate constants for the two reagents. The results reveal that the intrinsic barrier to the electron transfer is relatively unchanged in the SAM, while the rate constant is somewhat depressed due to the long distance over which the electron must transfer, Electrochemistry, Marcus theory, Cross reaction.
