Synthesis of a nanoscale Cu()-oxo-carboxylate cluster, and effect of Cu-oxo cluster size on visible-light absorption

Cu 16 -Cu 31 Cu( ii )-oxo-carboxylate clusters are reported, including those with condensed 1.5 nm Cu-O cores supported exclusively by O-donor ligands. A size-colour correlation is observed due to a red-shift of the charge transfer absorption band on increasing size; hence these clusters sit between...

Description
Summary:Cu 16 -Cu 31 Cu( ii )-oxo-carboxylate clusters are reported, including those with condensed 1.5 nm Cu-O cores supported exclusively by O-donor ligands. A size-colour correlation is observed due to a red-shift of the charge transfer absorption band on increasing size; hence these clusters sit between small molecules and (black) CuO nanostructures. A Cu 31 -oxo cluster is discovered forming a link between small molecules and CuO nanoparticles.
