Demonstration of property change of a surface in response to an external stimulus through mechanical motion at the molecular level

We successfully developed a system in which the translocation of a ring along a peptide-based thread, induced by changes in the nature of the local environment, could be used to switch the fluorescence of a rotaxane on or off. Remarkably, the system not only works in solution but also in polymer films where patterns visible to the naked eye can be generated solely through controlled submolecular motion. A polymer film INHIBIT logic gate based on a combination of control of submolecular positioning and chemical modification (protonation) was also demonstrated.
