| Outline of Final Research Achievements |
Recently, mechanophores that change absorption and fluorescence properties responding to mechanical stimuli have been extensively studied. In this study, we developed a supramolecular mechanophore based on cyclophane. When cyclophane-based supramolecular mechanophores with one fluorophore and one quencher are introduced into polyurethane, the film obtained through solvent casting shows an orange fluorescence color derived from the charge-transfer complex between the fluorophore and quencher. When the film is stretched, the fluorophore and quencher are spatially separated and blue fluorescence from the fluorophore is observed. This ratiometric fluorescence color change is instantly reversible.
