Abstract :
Magnetic field induced change in the pyrene-N,N-dimethylaniline exciplex fluorescence has been studied in condensed phase with very high permittivity. In contrast to the commonly observed enhancement of exciplex fluorescence in presence of magnetic field (for 7 < ε < 33), the effect shows a complete reversal at low DMA concentration in DMSO which is observed only at the blue end of fluorescence. At high DMA concentration the negative MFE at blue end slowly reverts back to the normal. At the red end of the emission the MFE retains its normal character for all donor concentrations even at very high permittivity.
