Abstract

Homochiral DyIII complexes: By changing the ligand-to-metal ratio, enantiomeric pairs of a DyIII complex of different nuclearity could be obtained. The mono- and dinuclear complexes exhibit characteristics of single-molecule magnets and different slow magnetic relaxation processes. In addition, the dinuclear complexes (see picture) exhibit ferroelectric behavior, thus representing the first chiral polynuclear lanthanide-based single-molecule magnets with ferroelectric properties.
