Nanoporous materials are ubiquitous and indispensable in daily life as adsorbents. The discovery of a new porous compound having unique properties based on intrinsic nano-sized space and surface functionalities is scientifically and technologically important. Recently, porous coordination polymers (PCPs) or metal organic frameworks (MOFs) have been extensively studied because they can provide variety of nano-sized space in their stable frameworks by taking advantage of the features of “metal complex”. Now, many unusual porous functions have been achieved in this class of compounds, which have not been found in the traditional materials. In this accounts, we focus on the synthesis and functionalization of porous coordination polymers and their unusual selective sorption properties. Here, the following topics have been reported; 1) highly controlled acetylene accommodation in one dimensional channel, 2) a molecular gate exhibiting a locking / unlocking system in the nano-channel, 3) selective sorption of O₂ and NO in a TCNQ based porous coordination polymer utilizing charge transfer interaction, and 4) on-demand photochemical guest trapping and conversion by a light-responsive porous coordination polymer.
