Mimicking Photosystem II Reactions in Artificial Photosynthesis

Hammarström, Leif; Sun, Licheng; Magnusson, Ann; Frapart, Y; Berglund-Baudin, H; Åkermark, Björn and Styring, Stenbjörn LU (1999) In Zeitschrift für Physikalische Chemie 213(2). p.157-163
Abstract
The paper describes a project aiming at the construction of functional mimics of the oxygen evolving complex of Photosystem II, coupled to photoinduced charge separation. Biomimetic electron donors - manganese complexes and tyrosine - have been linked to a Ru(II)-polypyridine photosensitizer. Oxidation of the donors by intramolecular electron transfer from the photo-oxidized Ru(III) complex was demonstrated using optical flash photolysis and EPR experiments. A step-wise electron transfer Mn → tyrosine → Ru(III) was demonstrated, in a sequence analogous to reactions of the PSII donor side.
