摘要：
A novel fluorescent turn-off sensor JM for hypochlorite was synthesized. JM showed a remarkable selectivity for ClO− over diverse competitive analytes, including reactive oxygen species (ROS), via deprotonation reaction. Detection limit for ClO− turned out to be 0.60 μM. Sensor JM successfully determined ClO− in natural water samples with satisfactory recovery. The sensing mechanism of JM to hypochlorite was demonstrated by fluorescent and UV-visible spectroscopy, ESI-mass, NMR titration and TD-DFT calculations.
