Highly sensitive and selective chemosensor for the determination of palladium(II) cations based on diphenylphosphino derivative of N-aminofluorescein was synthesized. The Pd2+ ion detection is accompanied by a contrast chromogenic “naked-eye” effect of the bright red coloration of an acetonitrile solution and an increase in the fluorescence intensity by 88 times.
