Uncovering Structural Opportunities for Zirconium Metal-Organic Frameworks via Linker Desymmetrization.

ABSTRACT: The discovery of metal-organic frameworks (MOFs) mimicking inorganic minerals with intricate topologies requires elaborate linker design guidelines. Herein, the concept of linker desymmetrization into the design of tetratopic linker based Zr-MOFs is applied. A series of bent tetratopic linkers with various substituents are utilized to construct Zr-MOFs with distinct cluster connectivities and topologies. For example, the assembly between a bent linker L-SO₂ with C _2v symmetry and an 8-connected Zr₆ cluster leads to the formation of an scu topology, while another flu topology can be obtained by the combination of a novel 8-connected Zr₆ cluster and a bent linker L-O with C ₁ symmetry. Further utilization of r
