Self-assembling Process of Alkanethiol Monolayers on Gold Surface via Underpotential Deposition

摘要

It was demonstrated feasible that underpotential deposition(UPD)of copper on a monolayer-modified gold substrate can be used to determine the gold electrode area.The deposition and stripping of a Cu adlayer can take place reversibly and stably at a bared or a self-assembled monolayer modified gold electrode.The growth kinetics of decane-thiol/Au was also investigated via Cu UPD.The difference between the assembling kinetics determined by UPD and that by quartz crystal microbalance measurements reveals the configuration transmutation of the assembled molecules from a disordered arrangement to an ordered arrangement during the self-assembling processes
