摘要	In this study, a novel fluorescein-derived Schiff-base ligand bearing a chromone moiety which was called 6-Hydroxy-3-formylchromone fluorescein hydrazone (1) has been designed, synthesized and evaluated as a Mg2+ "turn on" fluorescent probe. This probe 1 exhibited high selectivity and sensitivity towards Mg2+ over other important metal ions investigated, and the remarkable enhancement in fluorescence emission centered at 504 nm was observed in the presence of Mg2+, which was attributed to the ring opening process of the fluorescein fluorophore in probe 1 upon complexation of 1 with Mg2+. Furthermore, the "turn on" response of this probe 1 to Mg2+ was nearly completed within 3 min, which indicated that this probe 1 could be utilized to sense and monitor Mg2+. for real-time detection.
