No evidence for dissociation of any of the aminophenols into aminophenolate ions in the monolayer or multilayer was found when adsorbed on silver nanostructures
(SNS). Surface-enhanced infrared absorption demonstrated additional hydrogen-bonding interactions in a multilayer of 2-aminophenol and 3-aminophenol adsorbed on SNS beyond what is present in the aminophenol powders. Surfaceenhanced
Raman spectroscopy (SERS) experiments also showed that a 2-aminophenol monolayer adsorbed on SNS is photolytically oxidized to either 3-aminophenoxazone or 2,2-dihydroxyazobenzene,
while neither 3-aminophenol nor 4-aminophenol showed any SERS activity.
