Shedding new light on the matter : Rather than the conventional approach of utilizing the cascade effect, charge separation can be stabilized in artificial photosynthetic systems simply by the geometry. In these latter systems, light‐induced charge separation (CS) in a closely spaced molecular dyad is followed by exceptionally slow charge recombination (CR, see picture) to give a charge‐separated state with a lifetime of up to 120 s.
