Abstract:

As we learn to measure the precise structures, environments, and functions of molecules at the molecular scale, we are learning to direct molecules into desired positions to create nanostructures, to connect functional molecules to the outside world, and to serve as test structures for measurements of single or bundled molecules. Hierarchical patterning enables simultaneous control at many levels, all the way from the macroscale through the microscale, ultimately to the subnanometer scale. Interactions within and between molecules can be designed, directed, measured, understood, and exploited. We examine how these interactions influence the chemistry, dynamics, structure, electronic function and other properties. Such interactions can be used to advantage to form precise molecular assemblies, nanostructures, and patterns, and to control and to stabilize function. New tools are needed and are being developed both for patterning and for measurements to advance this approach further.
