ABSTRACT
A fluorescent molecular probe R6G-Flu was prepared by modifying fluorescein onto Rhodamine 6G.The probe could be used to recognize Al3+ specifically, and the detection limit could reach as low as 10-8 mol/L.After addition of Al3+ (10 μmol/L) to the probe, the solution showed a color change from colorless to pink, and green fluorescence was observed under the UV irradiation, which could be perceived by the naked eye.By measuring the fluorescence emission intensity of R6G-Flu at different pH, the probe could also be used to determine pH in acidic pH range (3.00-6.00) and basic pH range (8.00-10.50).The detection results of Al3+ and pH indicated that the R6G-Flu was a dual-functional fluorescent molecular probe.
