A Ratiometric Fluorescent Probe for Selective Detection of Hypochlorite Anion
Zhijian Ou,Lei Shi,Wenli Huang,Shengzhao Gong,Haomei Liang,Haojia Hong 대한화학회 2017 Bulletin of the Korean Chemical Society Vol.38 No.12
A new fluorescent probe based on rhodamine and naphthalimide was synthesized for the discrimination of hypochlorite anion. Upon addition of NaClO, the emission intensities ratio (I576 nm/I528 nm) of the probe 1 increased quickly accompanied with the obvious change of color. The probe 1 also exhibited highly selectivity and fast response to hypochlorite anion. Furthermore, the newly proposed probe has been applied for natural water samples, and a satisfied result was obtained.
Selective and Fast-Response Fluorescent Probes for Hypochlorite and their Application

It is extremely important to develop selective and sensitive fluorescent probes for the detection of hypochlorite (HClO/ClO?). Herein, two ESIPT-based fluorescent probes (BS1 and BS2) were designed and prepared for the fast determination of HClO. The probes exhibited excellent specificity towards HClO and showed the rapid and huge fluorescent responses. Moreover, the probes BS1 and BS2 could sensitively detect HClO in the range of 0?100??M with the low detection limits of 87 and 106?nM, especially. Besides, the success of practical application in water samples and test strips suggested that the synthetic probes may be effective tools for the detection of hypochlorite in environmental samples.
