Anion binding in metal-organic frameworks

Despite commonly being used as the hosts for gases, solvents and other neutral molecules, metal-organic frameworks (MOFs) have received recent attention supramolecular anion binding with a broad range of environmental biological applications. The review summarizes development this area, anion-binding MOFs categorized based on different design strategies including cationic anion-exchange capabilities, that feature coordination to metal nodes, well functionalized non-covalent or covalent anion-recognition motifs. We also discuss advantages using MOF scaffold compared small-molecules receptors.
