Ion/Surface Reactions at Monolayers in Solution: A Combined Surface Enhanced Raman-X-Ray Photoelectron Spectroscopic Investigation of the Chemical Modification of a 2-Mercaptobenzothiazole Monolayer on Polycrystalline Au Films.

Reaction of a methyltriphenylphosphonium (TPP) ion with a 2-mercaptobenzothiazole (MBT) monolayer on polycrystalline gold under electrochemical conditions leads to the chemical modification of the monolayer. Surface-enhanced Raman spectroscopy (SERS) has been used to study the molecular nature of the transformation. MBT, which adsorbs in the thione form on… CONTINUE READING
