Artificial photosynthesis: towards functional mimics of photosystem II?

Hammarström, Leif ; Sun, Licheng ; Åkermark, Björn and Styring, Stenbjörn LU (1998) In Biochimica et Biophysica Acta - Bioenergetics 1365(1-2). p.193-199
Abstract
This paper describes the initial development of 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 photosensitiser. Oxidation of the donors by intramolecular electron transfer from the photo-oxidised Ru(III) complex was demonstrated using optical flash photolysis and EPR experiments. A step-wise electron transfer Mn->tyrosine->Ru(III) was demonstrated.
