| Research Abstract |
In the present work, the detailed local structure and dynamics in the proton conductive crystals and polymers including imidazole were investigated using solid-state NMR. The simulation analysis of deuteron NMR broad-line spectra and quadrupole Carr-Purcell-Meiboom-Gill (QCPMG) spectra was effective method for analyses of molecular motion in wide temperature range, multimode molecular motion and molecular motions in several domains in the materials. We clarified the proton conduction mechanism associated with reorientational motion of imidazole, proton conduction path, and factors hindering effective proton conduction. These informations are useful for development of novel proton-conducting materials.
