Porous Coordination Polymers (PCPs) are materials made up of metal ions or clusters linked by organic ligands, forming a three-dimensional network. Their unique structure creates pores, allowing them to absorb gases or liquids, making them useful in various applications like gas storage, separation, and catalysis. The tunable nature of PCPs enables researchers to modify their properties by changing the metal centers or organic linkers. This versatility allows for the design of materials tailored for specific functions, such as capturing carbon dioxide or storing hydrogen, contributing to advancements in materials science and environmental technology.
