Outline of Final Research Achievements

In the present work, the detailed analysis of local structure and dynamics in the proton conducting organic crystals and polymer composites including imidazole were performed to elucidate the mechanism of proton conduction. We tried to develop high proton conducting materials using material design based on the information of local structure and proton conduction mechanism. The isotropic rotation of imidazole molecule was found to play an important role in proton conduction. So simulation method of deuteron NMR spectrum for detailed analysis of isotropic rotation of proton carrier molecules was developed. The high proton conduction materials were obtained by improving mobility of imidazole molecule.
