Functional Composite Materials Based on Hydrogen-Bonded Organic Frameworks

Recent developments in supramolecular materials have focused on hydrogen-bonded organic frameworks (HOFs), which have quickly developed into a family of stable and useful crystalline porous materials by combining several intermolecular complementary hydrogen connections with other synthetic techniques. Because of the collective behavior of functional units with novel features, the regulated integration of HOFs with functional materials has produced new multifunctional composites with properties superior to those of their individual components. This perspective offers an overview of the significant advancements in the development of various multifunctional HOF composites made with HOFs and active species, including metal nanoparticles, MOFs, biomolecules, polymers, medicines, etc., for diverse applications like gas separation, catalysis, sensing, biomedicines, and antibacterial applications. Finally, the unresolved challenges and future developments in the field that require significant research efforts are discussed.
