Photosynthetic oxygen evolution involves water splitting into triplet oxygen, protons, and electrons, as follows: 2H2O → O2 + 4e −+ 4H. The reaction is catalyzed by the oxomanganese complex of photosystem II, embedded in the thylakoid membrane of green plant chloroplasts and internal membranes of cyanobacteria. Biomimetic synthetic complexes have been developed over the years, although the reac...
