Abstract
For the more satisfactory understanding of the dynamics and mechanisms underlying the photoinduced CS (charge separation) and CR (charge recombination) of produced CT (charge transfer) or IP (ion pair) state, we have conducted femtosecond-picosecond laser photolysis and time-resolved transient absorption spectral studies on various D (donor)-A (acceptor) composite systems such as those combined by spacers D-(CH2)n -A (n=l,2,3) or directly D-A, and on the uncombined fluorescer-quencher pairs as well as CT complexes in polar solvents. On the basis of the obtained results concerning the effects of D, A electronic interaction, energy gap for the reaction and solvent dynamics on the photoinduced CS and CR of produced IP states, a discussion is given on the photoinduced CS mechanism in biological photosynthetic reaction center.
