Strategies to generate larger pores in metal-organic frameworks

Metal-organic frameworks (MOFs) are porous crystalline materials assembled from organic ligands and metal nodes. Construction of hierarchically porous MOFs is vital to achieve the augmentation of pore size to mesopores or macropores, which can enhance the diffusion kinetics of guests and improve the capacity. Recently, researchers from Texas A&M University summarized the latest advances in MOFs with multi-level pore structures. Varying strategies to construct hierarchically porous frameworks, and applications in catalysis and encapsulation are discussed.
