摘要: Abstract Adsorption of purine DNA bases (guanine and adenine) on Cu(1 1 0) was studied by X-ray photoelectron spectroscopy (XPS), near-edge absorption fine-structure (NEXAFS), density-functional theory (DFT) calculation. At coverages near 0.2 monolayers, Angular-resolved NEXAFS analysis revealed that adenine adsorbates lie almost flat guanine are tilted up the surface with ring parallel to atom rows Cu(1 1 0). Referring previous studies pyrimidine [M. Furukawa, H. Fujisawa, S. Katano, Ogasawara, Y. Kim, T. Komeda, A. Nilsson, M. Kawai, Surf. Sci. 532–535 (2003) 261], isomerization found play an important role in adsorption geometry. Guanine, thymine cytosine have amine-type nitrogen next a carbonyl group, which is dehydrogenated into imine These bonded inherent portion –NH–CO– altered conversion enolic form dehydrogenation. Adenine contains no CO group participation amine parts, resulting nearly flatly-lying position.
