摘要: A simple, water-soluble, Fe³⁺-selective fluorescent probe, derived from rhodamine B, was synthesized and characterized. The probe exhibits a fluorescence response toward Fe³⁺ with acceptable sensitivity and selectivity and even facilitates visual or naked-eye detection of Fe³⁺. The experiment results show that the response of the probe to Fe³⁺ is pH-independent over a wide range of 4.0-10.0. In addition, fluorescence microscopic imaging experiments have proven that the probe is cell permeable and can be used for monitoring intracellular Fe³⁺ in living cells.
