Model Systems for Photosystem II

The development of model systems can make a significant contribution towards the progress of artificial photosynthesis by simultaneously providing information relevant for an increased understanding of the working principles of natural systems, and allowing a systematic approach to the synthesis of bioinspired systems that can be incorporated in working devices. 

The first studies of a synthetic system with a tyrosine bound to a [Ru(bpy)3] photosensitiser were performed in water, in the presence of methyl viologen as an electron acceptor.Irradiation of the complex

The reactions of the several manganese gluconate complexes with molecular oxygen and hydrogen peroxide have been studied in terms of stoichiometry and reaction kinetics. Reaction mechanisms are proposed on the basis of the kinetic data. In addition, the thermodynamic and mechanistic characteristics of an ideal model system for photosystem-II are analyzed and evaluated.
