Abstract
This tutorial review describes metal-based anion receptors in the context of first- and second-sphere coordination. Selected examples (case studies) are used to show how metal ions can be used to (1) organise hydrogen-bond donor sites on ligands in order to bind anions, (2) influence the conformation of ligands to enhance anion binding, (3) alter the binding conformation of a receptor depending on the solvent and (4) develop a receptor to target a specific anion (sulfate) for sequestration.Keywords
