The novel rhodamine fluorescent chemosensor was synthesized in five steps from 2-aminophenol and 3-(diethylamino)phenol. It exhibited very strong ?uorescence responses to Ca2+ and had remarkably high selectivity to Ca2+ than other metal ions. When the concentration of Ca2+ was in the range of 2×10-6~5×10-5 mol/L, there was a good linearity between the fluorescence intensity of the chemosensor and the concentration of Ca2+.

Key words: fluorescent chemosensor, rhodamine, calcium ion, recognition, fluorescence intensity
