| Abstract: | The preparation and cyclic voltammetric behaviors of self assembled monolayers(SAMs) containing electroactive viologen group have been investigated. neatment of this viologenSAM with solutions of alkanethiols results in replacing the electroactive thiol, shifting negativelyits formal potentials and decreasing its heterogeneous electron transfer constants along with theimmersion time. The aim of the work is to understand the exchange regularity of the mired SAMson gold electrode surfaCe. |
