Side-by-side: Two trinuclear copper-dioxygen species have been characterized by UV/Vis stopped-flow spectroscopy in solution—an asymmetric and a symmetric one being the final product of the oxygenation. For the first time, these rare biomimetic species could be stabilized by dianionic ligands by using perfluoropinacolate. The asymmetric trinuclear core is a true model for the active site of multicopper oxidases. Density functional calculations yielded further insights into the electronic structure and catalytic measurements prove the oxidation capability of the symmetric trinuclear core. More information can be found in the Full Paper by S. Herres-Pawlis, L. H. Doerrer et al. on page 8212.
