ABSTRACT
Thiophenols as high toxic environmental pollutants are poisonous for animals and aquatic organisms. Therefore, it is indispensable to monitor thiophenols in the environment. Herein, a novel near-infrared fluorescent probe was developed for the detection of thiophenols, which was easily prepared by one-step coupling of 2,4-dinitrobenzenesulfonyl chloride with Nile blue. The probe showed a significant near infrared (â¼675â¯nm) fluorescence "turn-on" response to thiophenols with some good features including chromogenic reaction, high sensitivity and selectivity, fast response, near-infrared emission along with low detection limit (1.8â¯nM). The probe was employed to rapidly and visually determine thiophenols in several industrial wastewaters with good recoveries (90-110%). Moreover, this probe has been demonstrated good capability for imaging thiophenol in HeLa cells.
