| Outline of Final Research Achievements |
In this project, we have established design guidelines for repeatable mechanochromic polymers that exhibit color change and fluorescent emission originated from the generated carbon-centered radicals based on polymer reactions in which specific carbon-carbon covalent bonds in polymer chains are selectively and reversibly cleaved by mechanical stimuli. We have succeeded in developing various reactive polymers by generating unique carbon-centered radicals that have relatively high stability even in air. By subjecting the mechanochromic polymers to equilibrium conditions, the carbon-centered radicals recombine to return to their original molecular skeletons. Furthermore, by investigating the relationship between the structures of mechanochromic molecules and the polymer reactions induced by mechanical stimuli, we were able to establish an academic foundation for polymer mechanochemistry.
