Dual-Functional Fluorescein-Based Chemosensor for Chromogenic Detection of Fe3+ and Fluorgenic Detection of HOCl.
A novel fluorescein-based dual probe was designed and synthesized. The probe exhibited highly sensitive and selective colormetric response to Fe3+ and turn-on fluorescence response towards OCl- with very low detection limits of 100 and 50 nM, respectively. It was successfully applied for quantitative detection of Fe3+ and OCl- in real water samples. Moreover, probe 1 was expected to be a potentially powerful tool for studying and providing further insights into OCl- and Fe3+ chemistry in the near future.
