dc.description.abstractEn | A new family of [Cu4L4] cubane complexes have been synthesized by the self-assembly of CuII salts and β-aminovinyl trifluoromethyl ketone ligands. The resulting polynuclear architectures were especially designed to exhibit magnetic properties arising from the metallic cubane architecture as well as electro- or photosensitive properties arising from the ligands. The optical and electrochemical behaviours of the compounds were measured in solution to confirm that the properties of the free ligands were retained within the elaborated complexes. DFT investigations of the organic moieties were conducted with the aim of assigning the observed electronic processes to the different redox steps and absorption bands. The crystal structures of the polynuclear complexes were solved and refined by single-crystal X-ray diffraction analysis and correlated to variable-temperature magnetic susceptibility data. The overall expected ferromagnetic behaviour of the [Cu4L4] complexes is weakly influenced by the ligand substitutions. Ab initio configuration interaction calculations helped us to detail the variations of the various magnetic exchange pathways. | |
