Abstract
Quenching of perylene fluorescence by AgClO4 and concomitant perylene…Ag+*) exciplex formation was studied in 15 organic solvents ranging in dielectric constants from 6 to 65 and in mixed aqueous organic solvent systems. In almost all of these solvents perylene fluorescence quenching and exciplex fluorescence occurred.—The maximum of the exciplex emission spectrum lay at 490 ± 5 nm independent of the solvent employed. Distinct variations of the extent of fluorescence quenching and of exciplex formation with nature of solvent were found. They are interpreted in terms of (i) solvent viscosity (ii) coordination between solvent and Ag+ ion and (iii) solvent structure due to the Ag+ ion solvation.Keywords
