Chromogenic and fluorogenic detection of a nerve agent simulant with a rhodamine-deoxylactam based sensor.
A chromogenic and fluorogenic detection of a nerve agent simulant was developed based on diethyl chlorophosphate triggered tandem phosphorylation and intramolecular cyclization of N-(rhodamine B)-deoxylactam-2-aminoethanol.
متن کاملFluorescent polymeric aggregates for selective response to sarin surrogates.
By combining the sensitivity of fluorescent units with the response of "smart" polymers to environmental changes, we propose a new approach for chemical detection applications. The system proved to be sensitive to 12 ppb of diethyl chlorophosphate (DCP), a Sarin surrogate, and to discriminate between the interfering molecules.
متن کاملHyperconjugation in diethyl ether cation versus diethyl sulfide cation.
Ionization of a molecule can greatly alter its electronic structure as well as its geometric structure. In this collaborative experimental and theoretical study, we examined variance in hyperconjugation upon ionization of diethyl ether (DEE) and diethyl sulfide (DES). We obtained the experimental gas phase vibrational spectra of DEE, DES, DEE(+), DES(+), DEE(+)-Ar, and DES(+)-Ar in the wavenumb...
متن کاملA rhodamine-deoxylactam based sensor for chromo-fluorogenic detection of nerve agent simulant.
N-(rhodamine B)-deoxylactam-5-amino-1-pentanol (dRB-APOH) was designed and prepared as the chromo-fluorogenic sensor for detection of a nerve agent simulant via analyte triggered tandem phosphorylation and opening of the intramolecular deoxylactam. The successful detection of diethyl chlorophosphate suggests the utility of rhodamine-deoxylactams as the chromo-fluorogenic signal reporting platfo...
متن کاملDiethyl pyrazine-2,5-dicarboxylate
The mol-ecule of the title compound, C(10)H(12)N(2)O(4), is located around an inversion center. The carboxyl-ate groups are twisted slightly with respect to the pyrazine ring, making a dihedral angle of 2.76 (19)°. In the crystal, mol-ecules are stacked along the c axis via weak C-H⋯O hydrogen bonds.
