A novel rhodamine-based probe L was synthesized from rhodamine B through "click chemistry". It showed that probe L acted as a naked-eye and "turn on" fluorescent probe for Fe3+, Al3+ and Cr3+ recognition.L is highly selective to trivalent ions (Fe3+, Al3+ and Cr3+) over other monovalent or divalent ions in CH3OH. Detection limits of probe L for Fe3+, Cr3+and Al3+ are 9.7×10-5, 6.9×10-5 and 1.4×10-4 mol/L, respectively, which could make it potentially applicable in Fe3+, Cr3+ and Al3+ detection.

Key words: rhodamine, benzothiazole, click chemistry
