Abstract: The recent advent of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) as new functional microporous materials, have attracted the attention of chemists and physicists due to not only scientific but also application interest in the creation of unprecedented regular nano-sized spaces and in the finding of novel phenomena.1-3 The recent advent of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) as new functional microporous materials, have attracted the attention of chemists and physicists due to not only scientific but also application interest in the creation of unprecedented regular nano-sized spaces and in the finding of novel phenomena.1-3 We have found flexible porous frameworks, which respond to specific guests, dissimilar to the conventional porous materials.4 This new class of materials encompasses possibility creating platform for porous functions. In this talk, three noteworthy properties (flexibility and softness, collectivity of spaces, and diverse structures) are emphasized as they should become increasingly more important as this material is developed. In addition, we have focused on mesoscopic domains and/or whole size of PCP crystals, and discovered unique functions regarding confinement, recognition, transportation and conversion of guest molecules, and responsiveness to chemical and/or physical stimuli.1-5 Based on the unique properties we would be able to apply PCPs to gas materials since low molecular weight molecules, such as carbon dioxide (CO2), hydrogen (H2), oxygen (O2), methane (CH4), acetylene (C2H2), nitric oxide (NO) and alkanes (C2–C3), are important gases for the global issues of energy, natural resources, the environment, and living systems.
