Abstract : Aniline-terminated self-assembled monolayers SAMs on gold surfaces have successfully reacted with ArSO 2 NHOSO 2 Ar Ar = 4-MeC 6 H 4 or 4-FC 6 H 4 resulting in monolayers with sulfamide moieties and different end groups. Moreover, the sulfamide groups on the SAMs can be hydrolyzed showing the partial regeneration of the aniline surface. SAMs were characterized by water contact angle WCA measurements, Fourier-transform infrared reflection absorption spectroscopy IRRAS and X-ray photoelectron spectroscopy XPS.

Keywords : sulfamide reversibility SAM gold surfaces hydrolysis IRRAS XPS
