Two fluorescent anion sensors bearing phenol, carbazole-NH and -NO 2 group were designed and synthesized. They both exhibited highly binding ability for H2PO4? among the anions tested. In the presence of H2PO4?, the fluorescence of the sensors underwent a dramatic enhancement, while the presence of other anions such as F?, AcO?, Cl?, Br?, and I?, had weak or no effect on the fluorescence. The determination limit of two sensors (1 and 2) toward H2PO4? were 3.0×10?7 and 5.0×10?7 molL-1, respectively. Theoretical investigation indicated it was the highest HOMO to induce the red-shift phenomena of two sensors.
