Abstract

Oxido-pincer ligands with phenolate-groups [2,6-bis(2-methoxyphenyl) pyridine (LOMe2), 2,6-bis(2-hydroxyphenyl)- pyridine (LOH2), 2,6-bis-(2,4-dimethoxyphenyl)-pyridine (LOMe4)] coordinate to Cu-II forming binuclear complexes which can be easily and reliably converted into mononuclear species. Their physical properties were analysed using EPR, optical spectroscopy and (spectro-) electrochemical methods. The results were compared to those of related Ni-II complexes and discussed in view of Cu-containing metalloenzymes. Due to the ligands flexibility the Cu-II/Cu-I redox couple exhibits high reversibility, while the ligand-centred oxidation leads to highly reactive phenoxy radicals. Reduction of the LOH2 complex leads to sequential deprotonation. The ligand LOMe4 and the derived complexes show blue luminescence, which can be rationalised from its molecular structure (analysed by XRD). (C) 2010 Elsevier B.V. All rights reserved.
