将磁性和光学特性集成到金属有机框架（MOF）中仍然是一个巨大的挑战。在此，我们通过结合基于[IrIII(ppy)2(bpy)]+的荧光金属配体和磁性LnIII中心合理地构建了两个3D磁光MOF。 Δ-或Λ-[IrIII(ppy)2(bpy)]+的交替排列赋予这些MOFs增强的光学性能。此外，DyIII 的使用会导致场引起的慢磁弛豫。该工作为磁光双功能MOFs的制备提供了有效的策略。
Integrating magnetic and optical properties into a metal−organic framework (MOF) remains a great challenge. Herein, we have reasonably constructed two 3D magnetooptical MOFs by incorporating a [IrIII(ppy)2(bpy)]+ -based fluorescent metalloligand and magnetic LnIII centers. The alternating arrangements of Δ- or Λ-[IrIII(ppy)2(bpy)]+ endow these MOFs with enhanced optical properties. Moreover, the use of DyIII leads to field-induced slow magnetic relaxation. This work provides an effective strategy for the preparation of magnetooptical bifunctional MOFs.
