molecular recognition at interfaces
Get PDFIn order to investigate molecular recognition on surfaces, an azide-
functionalized monolayer was deposited on gold. The monolayer was
characterized by X-ray photoelectron spectroscopy (XPS) and angle-resolved
near-edge X-ray absorption fine structure (NEXAFS) experiments and the
decomposition of the azide upon irradiation with X-ray beams was investigated.
Subsequently, various alkyne-functionalized host and guest molecules were
attached to the azide by 1,3-dipolar cycloaddition. These modified surfaces
and their host–guest chemistry were analysed by XPS and angle-resolved NEXAFS.
The reversibility of guest binding was shown for one example as a proof of
principle
