同手性Dy(III)配合物:通过改变配体与金属的比例,可以获得不同核的Dy(III)配合物的对映体对。单核和双核配合物表现出单分子磁体的特征和不同的慢磁弛豫过程。此外,双核配合物还表现出铁电行为,是第一个手性多核镧系单分子铁电磁体。
Homochiral Dy (III) complexes: by changing the ligand-to-metal ratio, enantiomeric pairs of a Dy (III) 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 exhibit ferroelectric behavior, thus representing the first chiral polynuclear lanthanide-based single-molecule magnets with ferroelectric properties.
