Abstract
[structure: see text] A new fluorescent probe 3 was synthesized, and it exhibited high selectivity for Fe(III) over other commonly coexistent metal ions in both ethanol and water. Upon the addition of Fe(III), the spirocyclic ring of 3 was opened and a significant enhancement of visible color and fluorescence in the range of 500-600 nm was observed.
