Hydrophilicity and oxophilicity of the isolated CaMn4O5 cationic cluster modeling inorganic core of the oxygen-evolving complex.

Abstract

Bond splitting and oxidation of water is known to be catalyzed in photosystem II, which consists of protein ligands and an inorganic core, CaMn4O5. In the present study, the redox properties of the isolated CaMn4Ok+ clusters and the effect of water on them were investigated by gas phase thermal desorption spectrometry and density functional theory (DFT) calculations.
