Electrochemical In-Situ Raman Study of Azobenzene Self-Assembled Monolayers on Gold

Abstract An electrochemical in-situ micro-Raman spectroscopy system has been built and used to follow the reduction/oxidation of functional groups within self-assembled monolayers (SAMs) on gold. For the first time, the different electrochemical accessibility of two typical azobenzene SAMs has been successfully addressed by using this system.
