Surface and Thin Film Phenomena

Well ordered molecular domains of 2-mercaptopyrimidine and 4,6-dimethyl-2-mercaptopyrimidine on gold have been imaged. In contrast to alkyl thiol films, where the arrangement is largely, if not exclusively, determined by the underlying gold lattice, intermolecular interactions between these molecules appear to be important. A striking 'side-on' arrangement of2-mercaptopyrimidine molecules has been observed.
