Direct Observation of Perchlorate Incorporation Induced by Redox Reaction of Ferrocene Terminated Self-Assembled Monolayer Studied by in site FT-Surface Enhanced Raman Spectroscopy

摘要

The incorporation of ClO_4~- 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 ClO_4~- was clearly observed and the band disappeared in its reduced state.On the other hand,when HNO_3 was used as a supporting electrolyte,the band attributed to NO_3~- was not observed in the oxidized form of 8FT.
