The employment of the [1+1] condensation approach for the preparation of new macrocyclic scaffolds (LN6 and LN3O3) towards high-performance Dy(III) single-molecule magnets (SMMs) with symmetry is described. Engineering of the macrocycles denticity from LN6 to LN3O3 leads to a mononuclear SMM with a large value of 1300 K. The experimental results are supported by calculations, which indicate relaxation of the magnetization the second-excited state.
描述了采用[1+1]缩合方法制备具有对称性的新型大环支架（LN6和LN3O3）以用于高性能Dy(III)单分子磁体（SMMs）。大环配体齿数从LN6到LN3O3的工程设计导致了一个具有1300 K大值的单核SMM。实验结果得到了计算的支持，计算表明在第二激发态下磁化强度的弛豫。
