Our group studies molecular nanoscience, focusing on how molecular structure and organization control the properties of systems ranging from single-molecule junctions and surface-bound monolayers to extended molecular materials. These systems allow us, for example, to evaluate individual molecules as electronic circuit elements (e.g., wires or switches), investigate chemical processes at reactive interfaces, and explore how molecular organization and interactions give rise to the properties of larger assemblies. Our interdisciplinary approach combines the design and synthesis of new compounds with electrochemical and scanning probe microscopy-based characterization methods. Ultimately, we seek to understand and control charge transport, molecular self-assembly, and chemical reactivity at the nanoscale, establishing principles for the rational design of functional molecule-based materials and interfaces.
