| Outline of Final Research Achievements |
We have succeeded in the fabrication of monolith suprastructures of metal-organic frameworks or porous coordination polymers (MOF/PCP), which showed the flexible structural deformation in response to guest molecule accommodation. In this system, even though the crystalline of flexible MOF/PCP were integrated into three dimensional monolithic structure, the structural flexibility was maintained. This is an important step towards the control of microporosity by mechanical stress. In order to apply mechanical stress, the phase as soft matter would be more appropriate than the crystalline phase. Therefore, we also demonstrated a new method to fabricate soft matter like gels based on porous coordination polymers. Porous metal-organic polyhedra were used as porous monomers and interconnected by likers to form supramolecular polymers. The resulting gels were consisted of amorphous colloidal networks based on metal-organic polyhedra.

本成果により合成された、ゼリーように柔らかいゲル状の多孔性材料は、様々な形態に成形することが可能である。そのため、必要な場所に、必要な形で、必要な量の多孔性材料を合成することができる。これらは、今後、ガス分離膜、分離用微細管、センサーデバイスなどへと応用することが可能である。また、微小なコロイド粒子中には細孔が存在し、様々な分子（例えば蛍光分子や、薬剤など）を閉じ込めることが可能であるため、新しい薬剤運搬材料として利用することも期待される。
