摘要：

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.
