Everything is connected: DFT calculations show the connection between the highlighted charge‐transfer complexes of an oxidized organic photosensitizer (D + ) and I − , as well as I 2 − , and the complete redox process: a two‐step one‐electron transfer pathway (A), as well as an alternative pathway (B), which involves D + and I 2 − directly (see scheme).
