Creation of well-ordered functional molecular arrays at the nanometer scale is one of the key issues in the development for future molecular- or nano-electronic devices, solid-state quantum computation, single-electron devices, and biosensors. Molecular self-assembly on surfaces or surface nanotemplates via selective and directional covalent or non-covalent interactions offers a promising bottom-up approach to fabricating molecular nanostructure arrays with desired functionalities over macroscopic areas. The directionality and selectivity of intermolecular hydrogen bonding, metal-ligand interactions as well as covalent bonding can facilitate the formation of ordered supramolecular assemblies with good structural stability. In this talk, we highlight our recent progress in the fabrication of self-assembled molecular nanostructures on surface and surface nanotemplates, as investigated by in-situ scanning tunneling microscopy, with particular emphasis on the fabrication of 2D molecular dipole dot arrays.
