Structure of 2-mercaptomethylthiophene monolayers on Au(111)
The orientation of 2-mercaptomethylthiophene adsorbed on Au(111) was studied by near-edge X-ray absorption fine structure (NEXAFS). It was found that the orientation changed depending on the coverage of the molecules on Au(111); at low coverages the molecules formed striped islands in which the thiophene ring were inclined with a tilt angle of 45+/-10degrees from the surface normal, while at the saturated coverage they were aligned almost vertically with a tilt angle of 17+/-10degrees.
