Hydrogen-Bonded Organic Frameworks: Structural Design and Emerging Applications.

Constructing well-organized organic frameworks with tailor-made functionalities potentially boost multi-domain applications. Hydrogen bonding (H-bonding) is a category of general and weak intermolecular interaction, compared with covalent bonding or metal-ligand coordination. Porous frameworks mainly assembled by H-bonding (named hydrogen-bonded organic frameworks, HOFs) are intrinsically capable of decomposing and regenerating, a distinctive advantage to improve their processability while expanding the applicability. This paper summarizes the basic building concepts of HOFs, including feasible hydrogen bonded motifs, effective molecular structures, and their emerging applications.
