The fabrication methods of nanosystems and nanodevices follow two general approaches, top-down and bottom-up. Top-down methods essentially ‘impose’ a structure or pattern on the substrate being processed. In contrast, bottom-up methods aim to guide the autonomous ordering and assembly of atomic and molecular constituents into organized surface structures through processes inherent in the manipulated system. The latter approach presents a promising route to create even smaller functional systems with nanometer dimensions that are not accessible by top-down methods. It combines the ease of fabrication with exquisite control over the shape, composition and mesoscale organization of the surface structures formed.  We demonstrate how supramolecular self-assembly at well-defined surfaces can serve as an efficient tool for the bottom-up fabrication of functional structures and patterns on the nanometer scale. We focus on atomic-level investigations of self-assembled supramolecular architectures by employing mainly scanning tunneling microscopy. The exquisite structural details allow molecular level insight into the mechanisms and processes that govern the self-organization, which are generally not accessible. The presented exemplary molecular level studies elucidate the arrangement of organic adsorbates on metal surfaces, demonstrating the interplay between intermolecular and molecule–substrate interactions that need to be controlled for the fabrication of low-dimensional structures. The understanding of metallosupramolecular organization and intermolecular interactions on solid surfaces is important for the control of structure and concomitant function. . © nanoAC . . . . . . . . . .
