摘要：

The excited state dynamics of polyfluorene and the dynamics of the photoinduced electron transfer from polyfluorene to a C-60 derivative have been studied with time-resolved pump-probe measurements at low excitation density. Using the stimulated emission and photoinduced absorption spectra, the decay of the neutral excited state and the growth of the ionic excited state have been time resolved; the photoinduced charge transfer reaction occurs with a characteristic time constant of approximately 3 ps.
