| Research Abstract |
Most of assembled metal complexes reported hitherto are constructed with a combination of appropriate bidentate organic spacers and trigonal, tetrahedral, and octahedral metal templates, in which the metal ions are used as joining parts. However, these are disadvantage from the viewpoint that the metal ions are not available as the reactive site and the formed nano-pores cannot change according to the molecular sizes or shapes. These problems will be settled by the use of the metal complexes modified with non-covalent interaction sites such as hydrogen bonding and hydrophobic ones. Previously, we reported some dinuclear metal complexes linked with a triple hydrogen-bond between the biguanidato and biuretato complexes. The objective of this research project is to construct novel nano-porous transition metal complexes assembled with only the triple-hydrogen bonding and hydrophobic interactions and to establish a new methodology for the preparation methods. In this project, we designed and prepared one-, two-, and three-dimensional coordination frameworks, such as helical, brick wall, ladder, honeycomb, square grid, parquet, diamondoid and more complicate connective compounds. The construction of coordination polymers with nano-porous frameworks using these methodologies are of great interest due to their potential functionalities such as size-selective molecular absorption, shape-selective catalysis, and ion-exchange. Here, we succeeded in preparation of a novel nano-porous metal complex that has been constructed from the metal complexes bearing non-covalent interaction groups such as hydrogen bonding and hydrophobic ones.
