Abstract

The fluorescence decay curves of 9,10-diphenylanthracene, fluoranthene, and pyrene quenched by the anion radical of tetracyanoquinodimethane (TCNQ) were determined by using time-correlated single-photon counting. A high viscosity mixed solvent of methanol and glycerol was used to eliminate collisional quenching and effects of diffusion of the energy-transfer measurement. The decay curves were analyzed according to Förster's theory of long-range resonance energy transfer. The critical quencher concentrations for energy transfer for each system are compared to those predicted from the overlap of the donor emission and the acceptor absorbance spectra. For each of the three donors the energy transfer is somewhat more efficient than predicted from the spectral overlap.
