Biomimetic Cubane-Type Manganese Complex: Structurally Inspired by Photosystem II

초록

A biomimetic system comprising a cubane-type tetranuclear complex with a [Mn4O4] center similar to the core of the oxygen-evolving complex (OEC) of photosystem II (PSII), which is responsible for producing molecular oxygen, was synthesized from bulky carboxylate ligands and manganese by an expedient process. The synergistic effect of the exterior ligands attached to the core and the interatomic interactions led to a cubane-type morphology. This study lays the foundation for further study of metallic complexes analogous to biotic matter and contributes to structural knowledge of the second coordination sphere. In addition, the findings may shed light on the mechanism of oxygen evolution during photosynthesis. © 2021 Korean Chemical Society and Wiley-VCH GmbH.
