Outline of Final Research Achievements

Recent years, "confined water" in narrow hydrophobic nanosapce have attracted significant attention. This is because confined water shows unique cluster structure and dynamic behavior which are quite different from those of the bulk derived from the restriction of hydrogen bonding without any interaction with the outer wall.
We focused on the bottom-up type metal-organic nanotubes reported by our group. Taking the advantage of bottom-up protocol, we have succeeded in syntheses and structural determination of a total of 16 metal-organic nanotubes, with the 5 kinds of aperture sizes. Also, we have successfully confirmed unique ice-tube formation and very high proton conduction realized in a hydrophobic channel of metal-organic nanotubes. This is the first experimental observation for synthetic nanotube systems.
