Title: Mesoporous aluminium organophosphonates: a reusable chemsensor for the detection of explosives

Abstract

Rapid and sensitive detection of explosives is in high demand for homeland security and public safety. In this work, electron-rich of anthracene functionalized mesoporous aluminium organophosphonates (En-AlPs) were synthesized by a one-pot condensation process. The mesoporous structure and strong blue emission of En-AlPs were confirmed by the N{sub 2} adsorption-desorption isotherms, transmission electron microscopy images and fluorescence spectra. The materials En-AlPs can serve as sensitive chemosensors for various electron deficient nitroderivatives, with the quenching constant and the detection limit up to 1.5×10{sup 6} M{sup −1} and 0.3 ppm in water solution. More importantly, the materials can be recycled for many times by simply washed with ethanol, showing potential applications in explosives detection. - Graphical abstract: Electron-rich of anthracene functionalized mesoporous aluminium organophosphonates can serve as sensitive and recycled chemosensors for nitroderivatives with the quenching constant up to 1.5×10{sup 6} M{sup −1} in water solution.

  • There is a need for sensitive detection of organophosphonates by inexpensive, portable instruments. Two kinds of chemical sensors, based on surface acoustic wave (SAW) devices and fiberoptic micromirrors, show promise for such sensing systems. Chemically sensitive coatings are required for detection. Data for thin films of the polymer polysiloxane are reported for both kinds of physical transducers. Both kinds of sensors are shown to be capable of detecting concentrations of diisopropylmethylphosphonate (DIMP) down to 1 ppm. 9 refs., 5 figs.

  • Synthesis of vanadyl(IV) organophosphonates VORPO{sub 3}{center_dot}nH{sub 2}O (with R = CH{sub 3}, C{sub 2}H{sub 5}, C{sub 6}H{sub 5}) has been investigated by reaction of VOSO{sub 4}{center_dot}5H{sub 2}O + RPO{sub 3}H{sub 2} under refluxing conditions in aqueous media. The influence of different parameters is discussed, and compounds are characterized by X-ray powder diffraction, TGA, IR, XANES, and EXAFS. For example, three crystallographic forms of VOC{sub 6}H{sub 5}PO{sub 3}{center_dot}2H{sub 2}O obtained differ from each other in the location of the trans water molecule in the layered structure.
  • For approximately thirty years, the facilities at Rocky Mountain Arsenal were used for producing, packaging, and shipping sulfur- and phosphorus-containing mustard, Sarin, and pesticides. Degradation and manufacturing by-products related to these species are analyzed quickly using a combination of accelerated solvent extraction and gas chromatography (flame photometric detector) to determine exactly how specific waste structure materials should be handled, treated, and landfilled. These by-products are extracted rapidly from heated samples of soil or crushed concrete using acetonitrile at 100 C and 1500 psi, then analyzed using a gas chromatograph equipped with a flame photometric detector in its phosphorus- or sulfur-selectivemore » mode. Thiodiglycol, the major hydrolysis product of sulfur mustard, must be converted to a trimethylsilyl ether prior to quantitation. Detection limits, calculated using two statistically-unbiased protocols, ranged between 2--13 {micro}g analyte/g soil or concrete.« less
