Outline of Final Research Achievements

It is s breakthrough in the field of science and technology that small artificial perturbation induces unidirectional transport of proton in solid materials. In this research project, we investigated artificial proton pump phenomena for asymmetric nano-channel of single crystals under moderate conditions. We detected electromotive force probably due to concentration gradient of proton hole produced by artificial proton pump for two kind of asymmetric crystals. In a series of artificial control of physical property of solid materials, color change was realized by adsorption of oxygen molecules into nano-channel of lanthanide ion doped metal-coordination complex crystals. Gas molecule adsorption into deformable metal-coordination complex crystals was also investigated.
