| Abstract | A facile one step reaction between 6-aminocoumarin and anthracene-9-carboxaldehyde has resulted in a novel fluorescent probe, 6-((anthracen-9-yl) methyleneamino)-2H-chromen-2-one (AC) which is capable of selectively detecting intracellular Cr3+ in contaminated living cells under a fluorescence microscope. The binding of AC with Cr3+ is well characterized by different spectroscopic techniques. The binding constant values in CH3CN-water (9 : 1, v/v) and methanol-water (9 : 1, v/v) solutions have been estimated to be 1.1 x 10(5) and 3.1 x 10(5) respectively using the Benesi-Hildebrand equation. The detection limit for Cr3+ is 0.5 x 10(-6) M. The developed method has been used for speciation studies in a fast and environment friendly way using least amounts of samples, non-hazardous chemicals and solvents. |
