Abstract

Monolayers were formed from alkyl chain molecules having large in-plane dipole moments. The molecular species introduced was a sulfone moiety, and it was found that its incorporation strongly affected the molecular conformation within the monolayer. The effect of varying the position of the sulfone group in an otherwise straight alkyl chain, while constant molecular length was maintained, was studied, and the results were compared to those found for an octadecanethiol (ODT). The monolayers were characterized by Fourier transform infrared reflection absorption spectroscopy and X-ray photoelectron spectroscopy and by their wetting properties.
