Resumo(s)
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-dini trobenzenesulfonyl chloride with Nile blue. The probe showed a significant near infrared (∼675 nm) fluores cence “turn-on” response to thiophenols with some good features including chromogenic reaction, high sensi tivity and selectivity, fast response, near-infrared emission along with low detection limit (1.8 nM). The probe
was employed to rapidly and visually determine thiophenols in several industrial wastewaters with good re coveries (90–110%). Moreover, this probe has been demonstrated good capability for imaging thiophenol in
HeLa cells
