Photoinduced Symmetry-Breaking Charge Separation: The Direction of the Charge Transfer

Even flow: Photoinduced symmetry‐breaking charge separation takes place in a few picoseconds in a 1,3‐bis(perylene)propane dyad in polar solvents. Polarized transient absorption measurements show that the direction of the charge flow is random and entirely governed by the fluctuations of the solvent...

Description
Summary:Even flow: Photoinduced symmetry‐breaking charge separation takes place in a few picoseconds in a 1,3‐bis(perylene)propane dyad in polar solvents. Polarized transient absorption measurements show that the direction of the charge flow is random and entirely governed by the fluctuations of the solvent orientation around the dyad.
