Molecular machines in the gas phase

Mechanically interlocked molecules are proving useful structural prototypes for helping realize the concept of artificial molecular machinery. What makes these molecular systems so unique is that the non-covalent interactions between their components can be manipulated by external stimuli, enabling control over intra-molecular motion. We have used high-resolution spectroscopy on isolated molecules seeded in supersonic expansions to study these interactions and explore the conformational landscape of these systems. By "dressing" them with a controlled number of solvent molecules we are able to investigate the role of solute-solvent interactions and steer the interactions between the components.
