| Abstract: | Two new dinuclear copper(II) metallacyclophanes with 1,4‐disubstituted 9,10‐anthraquinonebis(oxamate) bridging ligands are reported that can reversibly take and release electrons at the redox‐active ligand and metal sites, respectively, to give the corresponding mono‐ and bis(semiquinonate and/or catecholate) CuII2 species and mixed‐valent CuII/CuIII and high‐valent CuIII2 ones. Density functional calculations allow us to give further insights on the dual ligand‐ and metal‐based character of the redox processes in this novel family of antiferromagnetically coupled di‐ copper(II) anthraquinophanes. This unique ability for charge storage could be the basis for the development of new kinds of molecular spintronic devices, referred to as molecular magnetic capacitors (MMCs). |
