1-Pyrenesulfonic Acid (sodium salt)

A fluorescent probe; abs/em = 346/376 nm, respectively; fluorescence can be quenched by ferric ions and the nitroaromatic compounds and explosive components 2,4-DNT and TNT in aqueous solutions; fluorescence quenching has been used in study of reverse micelles, including intermicellar migration of reactants and in the estimation of the number of micelles per cluster; has also been used as a surfactant and dopant in the synthesis of polypyrrole micro- and nanowires
