A new receptor 1 has been designed and synthesized. The open cavity of 1 selectively recognizes H2PO4- over a series of other anions in CH3CN containing 0.01% DMSO by exhibiting a ratiometric change in emission. In sensing, the cooperativity of the azaindoles in 1 has been proved using the model compound 2. Also the interaction behavior of the nitrogen in the azaindole has been proved by considering compound 3, which did not show any discrimination towards the anions. Binding studies have been carried out using fluorescence, UV-vis, 1H NMR and 31P NMR spectroscopic techniques.
