Abstract

4,4′-Diaminostilbene (DAS), its monoprotonated and diprotonated forms exhibit fluorescence. Their UV absorption and fluorescence emission spectra in different solvents and proton concentrations have been measured. 4-Trimethylammonium-4′-aminostibene hydrogen sulfate has been synthesized as a model for the monoprotonated DAS form. pK_a values in the ground state have been measured spectrophotometrically. The Stokes shifts in solvents of different polarities, the quantum yields and the apparent rate constants of trans-cis isomerization have been determined. Solvent polarity has a strong influence on spectroscopic properties.
