High‐Throughput Discovery of a Rhombohedral Twelve‐Connected Zirconium‐Based Metal‐Organic Framework with Ordered Terephthalate and Fumarate Linkers

Abstract

We report am etal-organic framework where an ordered arrayoftwo linkers with differing length and geometry connect [Zr 6 (OH) 4 O 4 ] 12+ clusters into at welve-connected fcu net that is rhombohedrally distorted from cubic symmetry.The ordered binding of equal numbers of terephthalate and fumarate ditopic carboxylate linkers at the trigonal antiprismatic Zr 6 core creates close-packed layers of fumarateconnected clusters that are connected along the single remaining threefold axis by terephthalates.T his well-defined linker arrangement retains the three-dimensional porosity of the Zr cluster-based UiO family while creating two distinct windows within the channelst hat define two distinct guest diffusion paths.T he ordered material is accessed by ar estricted combination of composition and process parameters that were identified by high-throughput synthesis.

A Novel Aluminum‐Based Metal‐Organic Framework with Uniform Micropores for Trace BTEX Adsorption

“…It is in the hexagonal crystal system with molecular formula (C 33 H 24 Al 3 O 15 ) and has the space group of P31c with lattice parameters a = b = 21.93(3) Å and c = 6.62(2) Å (Table S1), obtained by Single-crystal X-ray diffraction (SC-XRD) analyses. [13] The atomic percentages of ZJU-620(Al), identified by energy dispersive spectroscope linear scans, are C of 55.70 %, O of 33.23 % and Al of 11.07 % (Figure S2, Table S2), in agreement with the molecular formula. ZJU-620(Al) is a 3D network framework, obtained by SC-XRD analyses, constructed by formate ligands, TMTA ligands and AlO 6 clusters.…”

A Novel Aluminum‐Based Metal‐Organic Framework with Uniform Micropores for Trace BTEX Adsorption

“…ZJU‐620(Al) is a white powder product (Figure 1) with colorless needle‐like crystalline (Figure S1). It is in the hexagonal crystal system with molecular formula (C 33 H 24 Al 3 O 15 ) and has the space group of P 31 c with lattice parameters a = b =21.93(3) Å and c =6.62(2) Å (Table S1), obtained by Single‐crystal X‐ray diffraction (SC‐XRD) analyses [13] . The atomic percentages of ZJU‐620(Al), identified by energy dispersive spectroscope linear scans, are C of 55.70 %, O of 33.23 % and Al of 11.07 % (Figure S2, Table S2), in agreement with the molecular formula.…”

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

“…Among the thousands of reported metal‐organic frameworks (MOFs), [ 1‐11 ] Zr‐based MOFs have been widely investigated in the past several years, [ 12‐17 ] in part due to their robust frameworks with unique topologies, chemical and hydrothermal stabilities. Among them, this subclass of Zr‐MOFs built from hexanuclear Zr‐oxocarboxylate clusters has attracted great attention of chemists and materials scientists, [ 18‐27 ] such as now commercially available as UiO‐66. [ 19 ] These cluster‐based Zr‐MOFs are often synthesized directly from Zr 4+ ions and organic ligands.…”
