Abstract

A new rhodamine-derived Schiff base RH was synthesized and its sensing behavior toward various metal ions was investigated by UV-vis and fluorescence spectroscopic techniques. The sensor exhibited highly selective and sensitive colorimetric response to Cu²⁺ and Al³⁺, and "off-on" fluorescence response toward Fe³⁺ in semi-aqueous media. The spectral changes obtained are large enough in the visible region of the spectrum and thus enable naked-eye detection. Experimentally proved that the formation of RH-Al³⁺ complex is fully reversible and can sense to AcO^-/F^- via break the complex. The results revealed that the sensor offers the sequential detection of Al³⁺ and AcO^-/F^-.
