摘要：

Electrochemical characterization of Au electrodes covered with self-assembled monolayers of 2-mercaptobenzthiazole (Au/MBT) is described. Au/MBT is found to virtually block the underpotential deposition (UPD) of copper while offering no barrier to the heterogeneous electron transfer of the ferro-/ferricyanide redox couple. Potential-dependent ''opening'' and ''closing'' of MBT monolayer to Cu UPD observed in this study reveals the possibility of devising potential-dependent gates.
