We place single molecules, as well as pairs, lines, clusters, and larger groups of molecules into precisely controlled environments on surfaces. Monolayer matrices and inserted molecules and sub-assemblies can be designed so as to interact directly, to give stability or other properties to supramolecular assemblies. The exposed interface can be engineered to control physical, chemical, electronic, and biological properties. New families of molecules, particularly upright, symmetric cage molecules, are being developed to yield even greater control and are enabling determination of the key design parameters of both the molecules and assemblies. This, in turn, is enabling hierarchically controlled chemical patterning and selective functionalization from the subnanometer to the centimeter scales. We are simultaneously developing a suite of metrology tools for these methods to give unprecedented information on the structures and properties of these assemblies.
