Selenophene (C4H4Se) monolayers on Au(111) were prepared by two different methods: ultrahigh vacuum (UHV) and atmospheric vapor adsorption method. Near-edge X-ray absorption fine structure (NEXAFS) and X-ray photoelectron spectroscopy (XPS) results clearly indicate that the two monolayers are in different chemical forms; selenophene is molecularly adsorbed under UHV condition, while it is dissociatively chemisorbed via the C-Se bond cleavage under atmospheric condition. The dissociative chemisorption under atmospheric condition is interpreted in terms of the trapping mediated adsorption in the presence of a high-pressure ambient gas phase.
