Evolution of Zr nodes in metal–organic frameworks

Reticular chemistry guided precise construction of zirconium-pentacarboxylate frameworks with 5-connected Zr6 clusters

“…To the best of our knowledge, HIAM-4040 is the first example of Zr-MOFs constructed using a pentacarboxylate-type linker with 5-connected organic linkers and 5-connected Zr 6 clusters, which is different from the reported 5-connected Zr 6 cluster in NU-500, where one monodentate carboxylate ligand exists. 50,51 A close structure analysis demonstrates that, similar to that in NU-1400, CBIIs are also packed between two rows of Zr 6 clusters as viewed along the a axis, where additional carboxylate groups are connected to the left/below or the right/above the Zr 6 cluster (Fig. S10†).…”

Recent Advances in Multifunctional Reticular Framework Nanoparticles: A Paradigm Shift in Materials Science Road to a Structured Future

“…5 ), when it was discovered that metal ions could be bound to charged bonding agents, such as carboxylates, leading to the formation of crystalline 2D structures. Then by ingeniously interlacing inorganic clustered SBUs with shape-defining connectors through formidable molecular bonds, a significant breakthrough was made [ 51 , 52 ]. During the initial stages of their development, the primary objective was centered on synthesizing new MOF structures.…”

Macroscopic alignment of metal–organic framework crystals in specific crystallographic orientations

“…1–7 They have attracted significant attention owing to their fascinating properties and versatile applications, including molecular separation and storage, 8–20 catalysis, 21–26 optics, 27–29 and sensing. 30–34 The combination of metal nodes and organic linkers allows for the creation of customizable pore structures within ordered arrangements, 1–3,5,6,35 catering to specific application requirements. 36–38 Over the past three decades, researchers have developed various strategies to tailor the properties of MOFs, such as exploring novel MOF structures, 39 conducting post-synthetic modifications, 40–47 and incorporating composites.…”
