Adding to the Arsenal of Zirconium‐Based Metal–Organic Frameworks: the Topology as a Platform for Solvent‐Assisted Metal Incorporation

Gaining control over the assembly of mesoporous Zr-based metal–organic frameworks (MOFs) with modifiable metal nodes remains a challenge. The the topology is intriguing, particularly if considering postsynthetic modification, as it presents large sodalite-like cages surrounded by 12 interconnected 1D channels that allow for efficient diffusion of guest molecules throughout the structure. Herein, we demonstrate the first Zr MOF with the topology, NU-1200, which was synthesized by controlling the geometry of the organic building unit. In addition, by using NU-1200 as a platform, we perform solvent-assisted metal incorporation to form single-site metalated nodes, a process that is characterized by single-crystal X-ray diffraction.
