In this contribution, the electrochemciacl deposition method is used to synthesize uncharged dibenzyl viologen (DBV0) firm on HOPG surface. Electrochemical property and surface structure of the molecular adlayer are characterized by employing a combination of cyclic voltammetry (CV) and scanning electron microscope (SEM). Consequently, the DBV0 molecules generated from the reduction of the corresponding DBV2+ molecules at the solid/liqid interface by applying suitable electrochemical potentials are able to physisorb and form a physisorbed adlayer on HOPG. The existence of the DBV0 adlayer on HOPG surface is also confirmed by its blocking effect with respect to the electron transfer at the interface of electroactive [Fe(CN)6]2+ molecules.Downloads
