The bigger picture

Challenges and opportunities:

  • Phenomenal success in metal-organic frameworks for the past two decades has been driven in part by reticular chemistry. The topology-guided reticular chemistry was based on strong bonds to connect building blocks for predictable structures, but the same principle has not been applied to metal-organic polyhedra (MOPs).

  • Zr-based MOPs are an exceptional material platform for achieving reticular chemistry. Their packing structures can be decoded into underlying topologies.

  • A new horizon for reticular chemistry has been opened for Zr-based MOPs and their solid-state packing.

Summary

In this perspective, we have uncovered that reticular chemistry—responsible for phenomenal success in metal-organic frameworks—can be extended to Zr-based metal-organic polyhedra (MOPs), a new porous platform emerging from metal-organic materials. Guided by the combination of organic ligands and anion clusters selected for MOP assembly, we can narrow down possible choices for topologies of MOPs packed in the solid state. The reticular topology table presented here will accelerate the discovery of new functional Zr-based MOPs, bringing a new horizon for reticular chemistry.
