Abstract

Abstract : A fluorescent sensor has been developed for selective detection of picric acid (PA) in water. Amine (–NH2 ) functionalization on the nanobead surface enhanced the efficiency of the sensor among a library of nitro-organics, cations and anions. Abstract : A solution as well as solid state based sensor has been developed for selective detection of picric acid (PA) in water. Oligo ( p -phenylenevinylene) (OPV) incorporated polystyrene nanobeads (PS-OPV-NH2 ) having an average size of 180 nm have been synthesized through miniemulsion polymerization. Amine (–NH2 ) functionalization was performed on the nanobead surface to enhance the efficiency of the sensor among a library of other nitro-organics and library of cations and anions.
