Outline of Final Research Achievements

We synthesized coordination polymers constructed from metal ions and bridging ligands for solid state ion conductors. Targeted mechanism of ion conductivity is uni-directional ion transport. A coordination polymer from Zn2+ ion showed highly anisotropic proton transport checked by impedance spectroscopy. The conductivity is above 10(-3) S/cm which is on the criteria of application. Doping of Co2+ion into the Zn2+ framework was successful and we were able to control domain structure of Zn2+/Co2+ parts in a single crystal. This would enable to have uni-directional ion transportation.
