Detection of chemical warfare simulants by phosphorylation of a coumarin oximate.
نویسندگان
چکیده
The detection of chemical warfare simulants is attained by the PET mechanism that gives an "off-on" fluorescent response with a half-life of approximately 50 ms upon phosphorylation of a reactive oximate functionality; the X-ray crystal structure of the oximate was also obtained and is discussed.

Detection and remediation of organophosphorus compounds by oximate containing organogels.
A series of supramolecular diamide organogels containing a reactive compound for the remediation of organophosphorus (OP) species, in particular OP chemical warfare agents (CWAs), has been prepared in DMSO. The organogels have been found to absorb, encapsulate and decontaminate various OP CWA simulants in situ. At high simulant concentrations the gels also undergo a gel-sol transition releasing...

متن کاملNon-proximate detection of explosives and chemical warfare agent simulants by desorption electrospray ionization mass spectrometry.
Desorption electrospray ionization (DESI) mass spectrometry is used for the selective and sensitive detection of trace amounts of explosives and chemical warfare agent simulants from ambient surfaces at distances of up to 3 meters from the mass spectrometer.
متن کاملSurface detection of chemical warfare agent simulants and degradation products
Chemical warfare agent (CWA) simulants as well as their degradation and hydrolysis products were detected from surfaces using thermal desorption ion mobility spectrometry (TD-IMS). CWA simulant materials that closely mimic the chemical structures of real CWA G/V-type nerve and S-type vesicant simulants were used in this study. Reduced mobility constants (K0) in air were reported for 20 compound...
متن کاملResearch on the Interaction of Hydrogen-Bond Acidic Polymer Sensitive Sensor Materials with Chemical Warfare Agents Simulants by Inverse Gas Chromatography
Hydrogen-bond acidic polymers are important high affinity materials sensitive to organophosphates in the chemical warfare agent sensor detection process. Interactions between the sensor sensitive materials and chemical warfare agent simulants were studied by inverse gas chromatography. Hydrogen bonded acidic polymers, i.e., BSP3, were prepared for micro-packed columns to examine the interaction...
