Adsorption of 5-halouracils on Au(111)

Popis výsledku v původním jazyce

The immobilization of 5-halouracils on Au(111) has been studied by soft X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. Multilayer and monolayer films of 5-chlorouracil were deposited on the Au(111) surface by evaporation in vacuum while films of 5-bromouracil were absorbed in two modes: from the gas phase under ultrahigh vacuum conditions and from solution. The photoemission spectra of C, N and O 1 s, Br 3d and Cl 2p as well as the absorptionspectra at the N and O K-edges were measured for monolayers of 5-halouracil films and the nature of the bonding with the Au(111) surface has been determined. From the angular dependence of the NEXAFS spectra at the O and K-edges, we conclude that these 5-halouracils are lying nearly parallel to the Au(111) surface. Distinct chemical states and surface adsorption geometry of the 5-BrU molecules for monolayer coverage prepared in two different ways have been found.
