Outline of Final Research Achievements

In this study, we adressed the development of nanostructured material systems that can response to mechanical stimuli in their structures and properties. For this purpose, we have attempted nano-structurization and introduction of multistimuli-responsivitity for the luminescent organic material which we previously developed. We also attempted to establish a mechanical stimuli-responsive nanosystem by introducing a photochromic molecule to the previsouly reported molecule that can organize into nanorings.
