Outline of Final Research Achievements

In this study, various polymers having a mechano-responsive unit in the mid-chain were designed and synthesized, and their mechanochromic property was evaluated by using electron paramagnetic resonances and UV-vis spectrum. In order to investigate the effect of the mechanochromic behavior, the crystalline, amorphous, and the polymer having different glass transition temperatures were selected.
As a result, a crystalline polymer having a mechano-responsive unit showed mechanochromic behavior when it was crystallized from a melting state. In addition, it was confirmed that longer polymer chains induce mechanochemical activation more effectively and found that, in the bulk state, the star polymer has higher sensitivity to mechanical stress compared with a linear polymer having similar molecular weight arm segment.
