Outline Activities
Objectives: Creation of functional metal-organic frameworks (MOFs) and multi-nuclear metal complexes, and new functional system based on metal complex-membrane composites.

Metal-organic frameworks (MOFs) and multi-nuclear metal complexes: Precise control of structure and properties, e.g. magnetic, dielectric, luminescent and porous properties. Elucidation of correlation behavior interlocking with dynamic motion of confined molecules in porous structure.

Metal complex-membrane composite: Direct synthesis of metal complex or MOF crystals in the liposome. Control of capture and release of molecules in/on the membrane. Highly efficient catalyst system based on lipophilic metal complexes and liposome. Control of domain structure using lipophilic metal complexes. Hierarchical and selective arrangement of different metal complexes on/in the liposome space.
