  • Classical photochemistry requires nanosecond excited-state lifetimes for diffusion-controlled reactions. Here the authors provide direct evidence for the elusive pre-association between radical ions and substrate molecules, enabling photoinduced electron transfer beyond the diffusion limit.

  • The photoinduced accumulation of redox equivalents is a challenging requirement for artificial photosynthesis. Now a molecule has been developed in which the sequential absorption of photons results in the temporary accumulation of two holes and two electrons. The employed strategy opens up new possibilities for charge accumulation under low photon densities.
