Outline of Final Research Achievements

The research project focused on a construction of innovative stimuli-responsive supramolecular materials based on molecular recognition chemistry and polymer science. This project reader created stimuli-responsive polymeric materials with construction-expansion via host-guest interactions. The polymeric materials remind us the movement of smooth muscle fiber. The project reader investigated (1) creation of supramolecular actuator with effective responsiveness, (2) creation of highly-tough supramolecular materials, and (3) supramolecular actuator with tough and stimuli-responsiveness. To realize each supramolecular materials, a movable cross-linking and a reversible cross-linking were important keyword to achieve innovative functions. Especially, based on new molecular design, a photo-stimuli-responsive supramolecular actuator constructed in this project demonstrated effective photo-responsiveness and toughness.
