Metal-organic frameworks (MOFs), also known as porous coordination polymers, are a group of organic-inorganic hybrid materials that have garnered considerable attention due to their unique structural properties and their potential for diverse applications. MOFs comprise self-organized metal ions that act as nodes and organic linkers that serve as connectors, resulting in a highly ordered and tunable porous structure. One of the key advantages of MOFs is their modularity, which enables the tailoring of the size, shape, and polarity of pores to accommodate different adsorbents, from small gas molecules to macromolecules such as proteins and enzymes. Integration of MOFs with different functional materials, such as graphene and polymers, has led to the development of novel composite materials with superior functionalities. Recent research has also revealed that introducing defects into nanoscale MOFs allows for fine-tuning of the pore hydrophilicity or polarity, which has significant implications for applications such as oil/water separation, water storage and harvesting, and hydrocarbon separation. This Collection aims to bring together original studies that attempt to boost the performance of MOFs in various applications by tailoring the physicochemical properties of porous structures and coupling MOFs with other active components.
