Resolving Anomalous Cage Escape in Fe(III) Photosensitizers: A Marcus Theory Framework.
The cage escape yield (ΦCE), i.e., the separation of the geminate radical pair formed upon bimolecular excited-state electron transfer, is a key parameter that governs the efficiency of photoredox transformations. For Fe(III) photosensitizers featuring doublet ligand-to-metal charge transfer excited states, ΦCE are not...
