pH-Triggered ionization of self-assembled monolayers investigated by in-situ surface plasmon resonance measurements
Self-assembled monolayers (SAMs) of 2-aminoethanethiolhydrochloride (AET) or 2-aminoethanethiolhydrochloride (AHT) were formed on gold substrate. Deprotonation and reprotonation of SAMs of AET and AHT ongold substrate were investigated by using time-resolved surface plasmon resonance (SPR) measurements. The changesof the terminal functional groups from ?NH3+Cl? to ?NH2 (vice versa) via the HCl and NaOH treatment were successfullydetected, based on the fact that the initially formed AET and AHT SAMs were assumed to be a zwitterion-like species,_NH3+Cl-.
