| Abstract
| - Thin films of a benzylic amide macrocycle, the common component of a wide class of mechanically interlockedmolecules, are prepared by vapor deposition on Au(111). The films are characterized by monochromatedX-ray photoelectron spectroscopy (XPS) and high resolution electron energy loss spectroscopy (HREELS).The relative amounts of carbon, nitrogen, and oxygen are consistent with the formation of intact molecularspecies. At monolayer coverage, the relative intensity of out-of-plane to in-plane phenyl ring vibrationalmodes indicates that the macrocycle adopts a nearly flat-lying conformation. The formation of a chemisorptionbond is evidenced by the presence of a Au−O stretching vibration and a low binding energy component inthe O 1s core level region assigned to interfacial bonding. A decrease in film order and the absence of apreferred molecular orientation is observed at higher coverages. Computer modeling of the adsorption of themacrocycle on the surface rationalizes the experimental observations.
