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