Intermolecular interactions between the fluorescent organic dyes Fluorescein, Fluorescein Diiodide, Eosin, Rose Bengal, Erythrosin, Phloxine, Phloxine B, Rhodamine 6G, Lissamine Rhodamine B200 and the non fluorescent Crystal Violet and Malachite Green in aqueous solution have been studied by fluorescence quenching and difference absorption spectrophotometry. Equilibrium constants for the interactions have been determined by the two techniques mentioned and are compared. Absorption and fluorescence spectra and rates of photolysis of solutions obtained by extracting aqueous solutions of the mixed dyes into organic solvents are described. |
