Abstract
It is observed that the lanthanide acetylacetonates (Ln(acac)3) quench the magnetic field effect of pyrene-dimethylaniline exciplex luminescence. The quenching rate constants (Q) for the different Ln3+ ions follow the same trend as was previously observed in the photolysis of quinones and ketones in micellar media. The parallelism of Qs with spin-only moments of Ln3+ ions puzzled previous workers. We have noted a correlation of Qs with the square-root of the de Gennes factor G = (g - 1 )2J(J + 1), and offer an explanation of our observation on the basis of Heisenberg exchange interaction.
