Dicopper(II) metallacyclophanes with electroswitchable polymethyl- substituted para-phenylene spacers
Double-stranded anionic dinuclear copper(II) metallacyclic complexes of the paracyclophane type [Cu2L2]4- have been prepared by the CuII-mediated self-assembly of different para-phenylenebis(oxamato) bridging li
Redox switching of the antiferromagnetic coupling in permethylated dicopper(ii) paracyclophanes
A unique magnetic electroswitching behavior has been observed in an oxamato-based permethylated dicopper(ii) paracyclophane; upon reversible one-electron oxidation of the double tetramethyl-substituted p-phenylenediamidate bridging skeleton, the spin alignment of the two Cu II ions (SCu = ) changes from antiparallel (OFF) to parallel (ON) in the resulting dicopper(ii) π-radical cation species.
