The photophysical processes involved in the electron donor‐acceptor thermally activated
delayed fluorescence (TADF) emitters are complicated and controversial. The recent …

Important fractions of the energy absorbed in natural and artificial photosynthetic schemes
are dissipated via fast internal conversion processes. In contrast, chromophores that …

Despite a diverse manifold of excited states available, it is generally accepted that the
photoinduced reactivity of charge-transfer chromophores involves only the lowest-energy …

In MLCT chromophores, internal conversion (IC) in the form of hole reconfiguration
pathways (HR) is a major source of dissipation of the absorbed photon energy. Therefore, it …
