Outline of Final Research Achievements

We have developed molecular separation membranes using metal-organic polyhedron (MOP) as molecular channels. MOP is a metal-organic cage-like complex possessing a nanospace at the core. We succeeded in hybridization of MOP and polymers by attaching polymer chains directly to the MOP periphery. The MOP-polymer hybrid is called "MOP polymer" and that provided a smooth membrane by a solution casting method. The MOP polymer membrane showed superior CO2 separation ability over N2, that promises the potential of our MOP and polymer hybridization approach for the membrane applications. In addition, we examined catalytic properties of the MOP core and had a clue for the application to a MOP membrane reactor that enables molecular separation and conversion in one device.
