| Outline of Final Research Achievements |
A thin film formed by a porous coordination polymer (PCP), which is a crystal with molecular-sized pores, with a thickness of 1 micron or less without gaps, is actively studied because it can be used for separation of a mixture of substances. Until now, PCP membrane had a random orientation of PCP. In this study, the PCP and the holes were aligned in one direction by peeling the PCP into nanosheets and re-stacking them into a membrane. Furthermore, it was clarified that the PCP, which changes the size of the pores depending on the environment, retains its properties by this film formation method.

| Academic Significance and Societal Importance of the Research Achievements |
これまでガスの分離膜は一定の大きさの穴を持っており、分子のサイズの違いによってこの穴を通れるか否か、が分離の鍵となっていた。これに対して本研究では、環境により大きさを変化させられる穴を持つ新しい材料を用いた膜の作成を行った。この材料が、膜化しても元の性質を失わないことを示したことで、既存の膜では分離が困難であった物質の分離を可能にするための礎になると期待される。
