Recent crystallographic studies have revealed that the structure of the OEC is an asymmetric Mn4Ca-cluster, which provides a blueprint to develop man-made water-splitting catalysts in artificial photosynthesis. Although it was a great challenge to mimic the whole structure and function of the OEC in laboratory, significant advances have recently been achieved. One of the most important advances is the synthesis of the artificial Mn4Ca-cluster that closely mimicked both the atomic and electronic structures of the OEC in PSII. The artificial Mn4Ca-cluster provides a structurally well-defined chemical model to understand the structure-function relationship of the natural Mn4Ca-cluster, and sheds new insight into the mechanism of the water-splitting reaction in PSII. The artificial Mn4Ca-cluster and its variants may open new avenues to develop new generations of artificial catalysts for photo water-splitting reaction from earth-abundant and non-toxic chemical elements in the future.
