Inorganic and organic anion sensing by azole family members

Anion sensing is one of the most important aspects of chemistry and interest towards anion sensing, directly or indirectly, is evident from publications of the last two decades. Anion sensing is an induced response in a receptor in terms of an optical change (color change, UV–Vis and fluorescence) or an electrochemical change due to the recognition of one or more anions. A variety of ligands, including amides, urea, crown ethers etc., have been...
