Abstract
Fluorescence quenching of 1-hydroxynaphthalene-4-sulfonate by water has been studied in methanol-water and ethanol-water mixtures. The fluorescence quenching has shown a significant deviation from the Stern-Volmer linearity at higher concentrations of water due to dynamic quenching along with transient effects and instantaneous quenching. Time-resolved fluorescence decay of the conjugate base of 1-hydroxynaphthalene-4-sulfonate in methanol-water mixture indicates the need of only one water molecule to hydrate the conjugate base aftermath of the dissociation of the photoacid.
