Cage‐Ligand Strategy for the Construction of Zr4(embonate)6–Based MOFs with Third‐Order Nonlinear‐Optical Properties

Comprehensive Summary Herein, we demonstrate a very useful strategy to construct cage‐based metal‐organic frameworks (MOFs) with third‐order nonlinear‐optical properties. More specifically, by employing the Zr4L6 (L = embonate) cages to assembly with N‐contained ligands and Mn2+/Zn2+ ions, four Zr4L6‐cage‐based MOFs have been synthesized and structurally characterized. Among them, a 3D framework with strong aromatic π − π stacking force exhibits a good optical limiting effect. By employing the Zr4L6 (L = embonate) cages to assembly with N‐contained ligand and Zn2+ ions, a 3D cage‐based framework with strong aromatic π − π stacking interactions exhibits a good optical limiting effect.
