The fastest electron transfer processes between molecular
donor/acceptor systems have been observed for solvent to solute
type reactions, where the number of solvent molecules participating
could be high. This might explain the very short electron transfer
times of < 100 fs observed.
Here the photo-induced electron transfer in a bridged
donor-acceptor system was studied by femtosecond
pump-probe spectroscopy with a time resolution of 15 fs.
After photoexcitation of the acceptor (nile blue) an electron is
transferred from the donor (ferrocene) with a time constant of 90~fs, i.e.
close to fastest electron transfer times in the solute/solvent systems.
