文摘

A rhodamine-based probe for Fe³⁺ was prepared and confirmed by X-ray crystallography. The probe exhibited highly selective and sensitive recognition toward Fe³⁺ with distinct color change. Interestingly, the probe-Fe³⁺ complex could detect CN⁻ according to the strong co-ordination ability of cyanide to Fe³⁺. The whole recognition mechanism was explored through Job's plot, MS data and theoretical calculations. Importantly, the probe was further used for detecting Fe³⁺ in living cells and mouse, which exhibited excellent fluorescence imaging.
