Metal-organic frameworks (MOFs) are hybrid materials composed of organic bridging ligands that connect metal ions or small metal clusters to form one-, two-, or three-dimensional crystalline networks. Their propensity to exhibit extremely high surface areas (beyond 6000 m2/g) and impressive porosities (up to 90% free volume) has attracted significant interest from scientists and engineers in designing porous MOFs for gas storage and separations. The facile tunability of MOF materials also allows for their engineering to suit many other applications such as catalysis, drug delivery, and molecular sensing.
