Metal-polymer-coordinated complexes: An expedient class of hybrid functional materials

Innovation in materials, aided by recent advancements in science and technology, is shaping a better future. Among these, porous materials, including covalent-organic frameworks (COFs), metal-organic frameworks (MOFs), organic polymers, zeolites, silica, and metal-polymer-coordination complexes (MPCCs), have garnered significant attention due to their rigid structure and higher stability with respect to humid conditions. MPCCs have been of particular interest lately. This review first compares MPCCs to MOFs and COFs, then focuses on their synthesis and properties. It also highlights the unique characteristics that distinguish MPCCs from MOFs and organic polymers. Subsequently, it discusses the use of MPCCs in generating polymeric gels and other applications such as catalysis, sensing, and adsorption/separation of organic molecules and gases. Finally, it delves into the challenges and prospects for their design, synthesis, characterization, properties, and applications. This review aims to guide researchers in exploring the potential of porous materials in various fields.
