Anion Recognition Employing ‐NH Linked Organic Moieties

This review mainly focuses on the design of organic receptors employing amide linkage. Review also highlights the sensing mechanism of different anions detected by amide based organic receptors in different medium. All the data collected in this review is from last two decades. Graphical representation of different mechanism applied for anion recognition, a) Binding site is directly linked to the signalling unit, b) A spacer acts as a connector between binding site and the signalling unit and c) Chemodosimeter approach, upon anion addition a new molecule formed which provides the signal.
