A novel amino‐functionalized polystyrene copolymer (PS‐NH2) was designed and synthesized with styrene and 4‐vinylbenzyl amine. Additionally, an amino modified glass (G‐NH2) was obtained as a carrier. (PS‐NH2/pyrene)/G‐NH2 fluorescent nanofibrous membrane [named (PS‐NH2/pyrene)/G‐NH2] was designed and prepared via electrospinning technique to detect representative saturated nitroaromatic (NAC) explosive vapor. The (PS‐NH2/pyrene)/G‐NH2 showed highly fluorescence stability in ambient condition and further displayed a high quenching efficiency of 70.9% toward trinitrotoluene (TNT) vapor (∼10 ppb) with an exposure time of 150 s at room temperature. The abundance of amino groups could effectively adsorb NACs and the binding of electron‐deficient NACs to the amino groups on the (PS‐NH2/pyrene)/G‐NH2 surface led to the formation of charge‐transfer complexes. The quenching constant (KSV) to TNT was obtained to be 1.07 × 1011 mL/g in gaseous phase with a limit of detection up to 2.76 × 10−13g/mL. Importantly, the (PS‐NH2/pyrene)/G‐NH2 showed notable selectivity toward TNT and 2,4‐dinitrotoluene vapors. Straightforwardly, the colorimetric sensing performance can be visualized by naked eye with a color change for detecting of different vapor phase NACs explosives. © 2018 Wiley Periodicals, Inc. J.

“…1,2 Many methods have been developed to detect TNT and DNT, such as, fluorescence sensing, 3 mass spectrometry, 4,5 electrochemical testing, 6 and gas and liquid chromatography. 18,19 For example, Guo et al 20 prepared polyvinylpyrrolidone/ pyrene/3-aminopropyltriethoxysilane/reduced graphene oxide nanonets by electrospinning from their blends and reported that the nanonets showed a quenching efficiency of 81% toward TNT vapor within 540 s at room temperature. Fluorescence sensing seems to be a facile and promising method according to the criteria mentioned above.…”

Trinitrotoluene (TNT) and dinitrotoluene (DNT) as the most common explosives are considered to be harmful to the environment and humans. Therefore, the detection of these explosives has been attracting more and more attention. And easily prepared polymer materials with high sensing performance are still in demand. In this study, two silicon-containing polymers, PCzSiO and PCzSiPh, are employed to detect the explosives TNT and DNT. PCzSiPh shows a better performance and the quenching efficiency of PCzSiPh films in TNT and DNT vapor can reach 91.0 AE 0.3% and 94.4 AE 0.3%, respectively, due to their loose molecular chain structure. Furthermore, the fluorescence quenching of PCzSiPh in TNT and DNT is little dependent on the thickness of the film. And the PCzSiPh films show good reversibility, good filmforming ability and high thermal and morphological stability, which suggest their potential application in the coating of detection devices.
