Dihydrogenphosphateselectiveanionreceptor 2 based on one carbazole and two indole moieties was designed and synthesized. Fluorescence and 1H NMR titration clearly showed that receptor 2 was a good sensor in the selective recognition for dihydrogenphosphate over other anions. Receptor 2 utilized two amide hydrogens, three amine hydrogens to bind anions. These five hydrogens formed concave structure
