The 4′-(4-tolyl)-2,2′:6′,2”-terpyridine adsorbed on the Au(111) herringbone structure has been studied by combining scanning tunneling microscopy and at. force microscopy. Mols. are controllably translated by electrons excitations over the reconstruction, except at elbows acting as pinning centers. Exptl. data supported by theor. calculations show the formation of coordination bonds between the mol. and Au atoms of the surface. Using force spectroscopy, we quantify local variation of the surface potential and the lateral force required to move the mol. The authors found an elevation of the diffusion barrier at elbows of the reconstruction of ∼100 meV compared to the rest of the surface.
