“…In 1984, Azuma and Newcomb reported the synthesis of a series of tin‐based macrocycles 32 and 33 50. Coordination studies with 32 showed that this family of macrocycles would form 1:1 and 1:2 host:anion complexes with chloride ions in acetonitrile solution,51 with stability constants ranging from 400 to 850 M −1 . …”

Anion recognition chemistry has grown from its beginnings in the late 1960s with positively charged ammonium cryptand receptors for halide binding to, at the end of the millennium, a plethora of charged and neutral, cyclic and acyclic, inorganic and organic supramolecular host systems for the selective complexation, detection, and separation of anionic guest species. Solvation effects and pH values have been shown to play crucial roles in the overall anion recognition process. More recent developments include exciting advances in anion‐templated syntheses and directed self‐assembly, ion‐pair recognition, and the function of anions in supramolecular catalysis.

Die Chemie der Anionenerkennung hat sich seit ihren Anfängen in den späten sechziger Jahren des 20. Jahrhunderts stark entwickelt. Anfangs waren nur positiv geladene Ammonium‐Cryptanden als Rezeptoren für Halogenid‐Ionen bekannt. Nun, am Ende des Millenniums, sind eine Vielzahl geladener und neutraler, cyclischer und acyclischer, anorganischer und organischer supramolekularer Wirte für die selektive Komplexierung, den Nachweis und die Trennung anionischer Gastmoleküle verfügbar. Bei der Anionenerkennung spielen Solvatationseffekte und der pH‐Wert eine entscheidende Rolle. In jüngerer Zeit wurden wichtige Fortschritte bei Synthesen mit anionischen Templaten, der durch Anionen gesteuerten Selbstorganisation, der Ionenpaarerkennung und der Funktion von Anionen bei der supramolekularen Katalyse erzielt.

“…8 Organic based receptors have been developed which rely solely on hydrogen bond donors such as amides. 23 Typically, the indispensable binding interactions can be classical non-covalent ranging from H-bonding to cation-π, 24 π-π stacking 25 or anion-π. 26 However, its definition is also extended to interactions involving aromatic moieties, 27 weak C-H hydrogen bonds 28,29 or interactions between halogen atoms and lewis bases.…”

Calixarenes are excellent macro cyclic platforms that can be functionalized with numerous organic moieties to show cooperative binding towards anions. Their characteristic structural features with the ease of functionalization offers the way to tune the size of receptor cavity. This has led to finely tune the binding site and central hydrophobic cavity for the specified anions. Calixarene based systems provide prospective commercial applicability's in anion sensing and helps in understanding complex binding interaction. Intending to decipher the detailed insight of anion-calixarene binding, the present review discusses the reports of calixarene compounds tested for their toxic anionic recognition ability.
