Direct observation of perchlorate incorporation induced by redox reaction of ferrocene terminated self-assembled monolayer studied by in situ FT-surface enhanced Raman spectroscopy
The incorporation of ClO4- into 8-ferrocenyloctanethiol (8FT) self-assembled monolayer (SAM) induced by the redox reaction at a gold wire electrode was demonstrated using in situ FT Raman spectroelectochemistry. Upon oxidation of the 8FT SAM, a band attributed to ClO4- was clearly observed and the band disappeared in its reduced state. On the other hand, when HNO3 was used as a supporting electrolyte, the band attributed to NO3- was not observed In the oxidized form of 8FT.
