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

“…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.…”

Multicomponent Metal‐Organic Frameworks

“…These defects indicate a lack of framework periodicity, therefore the material constitutes a range of different cluster and pore environments. In a related example, linear bdc and zig‐zag fumarate (fum) linkers were combined into a multicomponent zirconium(IV) MOF, [Zr 6 O 4 (OH) 4 (bdc) 3 (fum) 3 ], using a one‐pot process [17] . Each hexanuclear zirconium cluster is a 12‐connected node coordinated to six bdc and six fum linkers.…”
