摘要

The development of azo-heterocycle based anion receptors is a very important field for the supramolecular chemistry. These kinds of anion receptors possess a great deal of merits such as various host structures, wide adaptability, high selectivity and sensitivity. This review summarizes the main design principles, anion recognition abilities and recognition mechanism of the azo-heterocycle based receptors which having pyrrole, indole, imidazole and carbazole as recognition groups.
