| 英文摘要 | The understanding of the structure-function relationship of the oxygen-evolving center (OEC), a Mn(4)Cacluster, in photosystem II is impeded mainly due to the complexity of the protein environment and lack of rational chemical models as a reference. In this study, two novel Mn-4-oxido complexes have been synthesized and characterized, in which the peripheral ligands of the [ Mn-4(III)] core are provided by eight mu(2)-carboxylate groups and two neutral terminal ligands (pyridine or isoquinoline). This type of peripheral ligation is very similar to the Mn4Ca-oxide model complexes recently reported to mimic the OEC. The new Mn-4-oxide complex can catalyze the oxygen-evolving reaction in the presence of ButOOH as an oxidant. The structure and redox properties comparison of the Mn-4-oxido and Mn4Ca-oxido complexes provide important clues to understanding the functional role of Ca in the OEC in natural photosynthesis, and develop more efficient artificial catalysts for the water-splitting reaction in the future.
