| Abstract: | 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. |
