Abstract
Adsorption of dicarboxylic acids [2-(trifluoromethyl)terephthalic acid and α,ω-dicarboxyperfluoroalkanes] from a solution onto a fluorine-terminated silicon(111) [Si(111)] surface was examined. X-ray photoelectron spectroscopy and Fourier transform infrared attenuated total reflection revealed that one carboxyl end covalently bonds to the Si surface, and the other end is exposed at the monolayer−air or monolayer−liquid interface. The reactivity of exposed carboxyl groups in the monolayer was confirmed by the fact that the surface species can be converted to chloroformyl groups by chlorination reagents.
