Outline of Final Research Achievements

Metal-organic frameworks (MOFs) composed of metal ions and organic ligands possess regulated nanopores and their electronic properties can be controlled by varying the combination of the components. Electrically conductive MOFs are expected to show new functionalities generated from interaction of guest molecules into framework electronic properties and application of MOFs in nanosheet states will open further up their use in varied applications including thin film electronic devices. The aim of this work is to create highly-oriented conductive MOF nanosheets and reveal their electronic properties.
Air/liquid interfacial synthesis was applied for creating highly-oriented MOF nanosheets composed of triphenylene derivatives with high π electron activity and transition metal ions. The planar electric conductivity of the nanosheets recorded as highest in related MOF nanosheets.
