英文摘要We report a simple pyrene-based fluorescent probe, sodium 8-(2,4-dinitrophenoxy)pyrene-1,3,6-trisulfonate (hpts-dnp), for the ultrasensitive and visual detection of thiophenol in 100% aqueous media. the sensing mechanism of this method is based on nucleophilic aromatic substitution on hpts-dnp caused by thiophenol to afford a highly fluorescent product, 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (hpts). the extremely low fluorescence background of hpts-dnp and high quantum yield of hpts ensure the superior sensing performance toward thiophenol, including rapid responses, off-on detection mode and excellent sensitivity. the detection limit is as low as 0.49 nmol l-1 according to the measurements with a spectrofluorimeter. this probe also features good selectivity (response ratio of thiophenol to interferents > 30), precision (2.93%) and accuracy (102%). this approach could be applied for monitoring the thiophenol concentrations in environmental water samples. hpts-dnp also showed good cell permeation capacity and low cellular cytotoxicity, indicating further application in bioimaging studies.
