| Outline of Final Research Achievements |
In our laboratory, we have found reversible macroscopic motion of supramolecular aggregate was induced by photo-isomerization of doped azo-benzene derivative as a minor component. This phenomenon is similar to biological system, in which motion of molecules is hierarchically and cooperatively developed to induce macroscopic movement. In this research project, we made an attempt to develop “Scanning NMR Microscope” for investigating change at molecular level in supramolecular aggregate at spatial resolution of 100 micrometer by use of micro-coil NMR method. As a complementary approach of this “Scanning NMR Microscope”, enhancement of NMR signal was investigated by use of dynamic nuclear polarization.
