Ionic Interactions in Electroactive Self-Assembled Monolayers of Ferrocene Species.

Abstract

The electrochemical and interfacial behavior of two types of electroactive self-assembled monolayer systems is investigated at gold electrodes. The first type is a ferrocene-based surfactant (a redox surfactant) derived from (dimethylamino)methylferrocene via quaternization of the amino group with various n-alkylbromides. These have a long alkyl chain with 16 or 18 carbons in the chain pendent from the cationic ammonium group. We refer to these as C16 and C18. The second type is a ferrocene-based dimeric species with a disulfide functional group capable of providing a permanent anchor to the Au electrode, thus endowing monolayers of this species with exceptional stability towards desorption. The electrochemical quartz crystal microbalance (EQM) is used to monitor the mass changes which occur at the electrode surface during the redox processes of these two species.
