摘      要：A novel molecular probe system(NapTpa-dnbs)was prepared based on the chromophore napthalimide fused triphenylamine ***-dnbs was tuned to absorb a large fraction of UV and near-infrared *** turn-on fluorescent response of NapTpa-dnbs to thiophenol caused an increased fluorescent emission by a factor of 11.5 at 597 nm in a PBS buffer *** photoinduced electron transform(PET)process of the probe became less feasible with the addition of thiophenol than that of the free ***-dnbs demonstrated high selective and sensitive detection toward thiophenol with respect to other competitive amine *** detection limit was determined to be 2.03×10^?7 mol/L *** sensing process is rapid(3 min).NapTpa-dnbs can accurately detect the thiophenol with a qualified recovery in real water ***-dnbs on test strips can detect the thiophenol vapour in the atmosphere.
