Porous metal complexes (which is also called porous coordination polymer (PCP) or metal organic framework (MOF)) with the nanospace in the microporous region are crystalline solids with backbones constructed from metal ions and organic ligands as connectors and linkers, respectively. The most striking character of these porous materials is that we can design and create nanospaces having different chemical and structural features with choosing various building blocks. In this two decade, this material has attracted considerable attention and a large number of compounds that have exceptionally high void volume and unusually selective gas adsorption functions have been reported. In addition, it is found that some flexible compounds showed gate opening type abrupt gas uptake at certain pressure, which has not been realized in the other porous compounds. Recent researches proved that two functions, molecular recognition and structural transformation, can be integrated in a framework, realizing highly sophisticated functions of bio-molecules such as hemeprotein. In this article, we show history and development of porous metal complexes, and representative functions of porous metal complexes focusing on the authors' materials.
