  • Title: Ultrafast spectroscopy of the solvent dependence of electron transfer in a perylenebisimide dimer.
    Author: Holman MW, Yan P, Adams DM, Westenhoff S, Silva C.
    Journal: J Phys Chem A; 2005 Sep 29; 109(38):8548-52. PubMed ID: 16834252.
    Abstract:
    We investigate the photoinduced intramolecular electron-transfer (IET) behavior of a perylenebisimide dimer in a variety of solvents using femtosecond transient absorption spectroscopy. Overlapping photoinduced absorptions and stimulated emission give rise to complicated traces, but they are well fit with a simple kinetic model. IET rates were found to depend heavily on solvent dielectric constant. Good quantitative agreement with rates derived from fluorescence quantum yield and time-resolved fluorescence measurements was found for forward electron transfer and charge recombination rates.
