Dipicrylamine (2,4,6-2′,4′,6′-hexanitrodiphenylamine, DPA) has been used for the detection and extraction of metal ions, especially potassium; however, its capability as an anion sensor has not been reported to date. It contains a secondary amine (N-H), the proton of which can form H-bonds with anio...
