The adsorption of a large organic C@SUB 90@H@SUB 98@ molecule, known as the Lander molecule, is studied by Scanning Tunneling Microscopy (STM) on a Cu(110)surface.@footnote 1@ Manipulation experiments on isolated Landers anchored at step edges at low temperatures, reveal a restructuring of the Cu steps. Surprisingly, when the molecule is removed from the step, a tooth-like structure appears (two atomic rows in width), corresponding to the distance between the spacer legs within the molecule. Scanning Tunneling Spectroscopy measurements are in progress to investigate the electronic states of the Lander on Cu(110). This is the first prototype of more complex molecular machines able to selffabricate nanostructures with the prospect of developing planar and atomically precise interconnections of molecular nanodevices. Furthermore, by nanopatterning the substrate via O@SUB 2@ chemisorption and using this template for Lander adsorption, we show that it is possible to self-assemble long 1D molecular wires. This type of assembly opens new possibilities for ordering organic molecules on surfaces. @FootnoteText@ @footnote 1@ F. Rosei et al., Science 296, 328 (2002).
