10_08/2009Cover Picture: Tuning the Rates of Long-Range Charge Transfer across Phenylene Wires (ChemPhysChem 8/2009)

The central part of the cover picture shows that the rates for long-range charge transfer across covalent phenylene bridges can be very sensitive to the chemical substituents attached to the individual bridging units. The peripheral parts of the picture illustrate the flash–quench technique employed to investigate intramolecular charge transfer between a phenothiazine donor and a photochemically generated ruthenium(III) complex. On page 1203, M. E. Walther and O. S. Wenger explain their experimental findings in terms of donor-bridge energy matching for hole transfer.
