A “light-up” fluorescent probe based on TEMPO-oxidation for the detection of ClO- and application in real samples

A highly selective and sensitive fluorescence “light-up” probe PTH for ClO − has been developed, which is designed by a new strategy based on TEMPO-oxidation for the first time. PTH exhibits excellent properties including quick response (within 2 min), lower detection limit (63.7 nM), good linearity ( R 2  = 0.9863) and specific selectivity. More importantly, its application of detection ClO- in real samples has also been achieved.
