文摘
The adsorption of a TTF derivative (2-[9-(1,3-dithiol-2-ylidene)anthracen-10(9H)-ylidene]-1,3-dithiole, exTTF) on Au(111) has been studied by a combination of scanning tunneling microscopy, photoelectron spectroscopy, and theoretical calculations. The results indicate that the molecule−substrate interaction is dominated by the S−Au bonds. However, due to conformational reasons, only one of the two dithiole rings is in close contact with the surface. As a consequence, the interaction with the Au surface is much smaller (less than half) the interaction of TTF with Au(111), where the four sulfur atoms are in direct contact.
