A pair of air-stable double-decker Dy(III) macrocyclic enantiomers featuring sole fluoride axial ligands were designed and structurally and magnetically characterized. They displayed strong intramolecular ferromagnetic coupling and two-step relaxation of magnetization supported by the collinear arrangement of the magnetic anisotropy axes and obviously different outer Dy-F distances for two Dy(III) ions, respectively.
设计并对结构和磁性进行了表征的一对具有唯一氟轴向配体的空气稳定型双层Dy(III)大环对映体。它们表现出强烈的分子内铁磁耦合以及由磁各向异性轴的共线排列和两个Dy(III)离子明显不同的外层Dy-F距离所支持的两步磁化弛豫。
