| Outline of Final Research Achievements |
Heterogeneous junction of proton-conducting 2D Cu(II)-based MOF membrane and hydroxide ion-conducting 2D layered double hydroxide (LDH) membrane provided a proton rectification ratio as high as >200, which is the highest among the all-solid-state H+-OH- rectifiers.
A reversible 2D-to-2D structural transformation was demonstrated in MOF composed of Cu(II) ions and terephthalate ligands for the first time. This transformation led to a marked increase in in-plane proton conductivity of more than six orders of magnitude.
Cation radical salts of tetrathiafulvalene and its derivatives have been synthesized by combining with protonic Pt(II)-based complex anions. A salt exhibited metallic electronic conduction (1-2 S cm-1 at room temperature) and superprotonic conduction (2 x 10-2 S cm-1 at room temperature), which led to the highest ambipolar conductivity (2 x 10-2 S cm-1) among the molecule-based proton-electron mixed conductors.
