Abstract Precise control of the pore size and environment of metal–organic framework (MOF) is a necessary condition for achieving high performance of gas adsorption and separation. After nearly two decades of development, the synthesis of MOF materials has gradually evolved from exploration and trial to precise-design, including function-oriented microstructure design and optimization, pore size tailoring, and secondary building unit (SBU) modification. The unique pore environments of MOF materi...

Metal–organic framework (MOF) membranes with sub-nanometer channels have great potential in molecule selective transport, but the scalable and facile fabrication of flexible and thin membranes from stable MOF structures is difficult, which is the key to realizing practical applications. In this work, stable and ultra-small MOF nanoparticles act as “ordered porous monomers” and are interfacially polymerized with organic monomers into ultra-thin and flexible membranes. An ∼150 nm thin MOF active l...

Regulating the structure of metal-organic frameworks (MOFs) by adjusting the ligands reasonably is expected to enhance the interaction of MOFs on special molecules/ions, which has significant application value for the selective adsorption of guest molecules. In this work, two tricarboxylic ligands H3L-Cl and H3L-NH2 were designed and synthesized based on the ligand H3TTCA by replacing part of the benzene rings with C=C bonds and modifying the chlorine and amino groups on the 4-position of the be...

The separation of ethylene (C 2 H 4 ) from a mixture of ethane (C 2 H 6 ), ethylene (C 2 H 4 ), and acetylene (C 2 H 2 ) at normal temperature and pressure is a significant challenge. The sieving effect of pores is powerless due to the similar molecular size and kinetic diameter of these molecules. We report a new modification method based on a stable ftw topological Zr-MOF platform ( MOF-525 ). Introduction of a cyclopentadiene cobalt functional group led to new ftw-type MOFs materials ( UPC-61...

The ligand with flexible conformation can be obtained by modifying functional groups. We modified H4DCBA with -CH3/-CF3 groups to construct three Zr-MOFs, the torsion of the central benzene ring changes the topologies. The three Zr-MOFs showed high adsorption rates for Cr2O72-, and the CF3-functional groups enhanced the adsorption capacity of the UPC-49 for Cr2O72-.

The design of MOFs with functionalized groups as well as suitable pore space plays a momentous part in gas adsorption and separation. Herein, a new Zn-MOF (Zn4(BTB-NH2)3·xsolvent, UPC-98, H3BTB-NH2 = 2′-amino-5′-(4-carboxyphenyl)-[1,1′:3′,1″-terphenyl]-4,4″-dicarboxylic acid) was synthesized successfully by an amino-functionalized ligand (H3BTB-NH2) for light hydrocarbon adsorption and separation application. UPC-98 with twofold interpenetrating structure retains relatively high thermal stabilit...

A porous metal-organic framework [Ba(H2 LLOMe 2- )·DMF·H2O]·2DMF (UPC-2) (H4 LLOMe = 4',4'''-(2,3,6,7-tetramethoxyanthracene-9,10-diyl)bis([1,1'-biphenyl]-3,5-dicarbo-xylic acid N,N-Dimethylformamide [DMF]), which can act as an excellent chemiluminescence microreactor, is designed and constructed. In the framework of UPC-2, the catalytic Ba cluster and electron-rich anthracene fluorescent centers are fixed and interconnected in an orderly fashion, and this can shorten the energy transfer path an...

The designability and adjustability of pore structure are the vital advantage of metal-organic framework (MOF) materials for separation. Their exploration in the field of membrane separation is still inadequate, especially for the regulation of pore environment based on the inorganic secondary building unit (SBU). In this work, we have studied the effect of the pore environment regulated by SBU on the gas separation permeance of MOF membranes for the first time. The imidazole (IM) molecules are ...

To achieve selective adsorption of ions and light hydrocarbons by changing the pore structure, Zr-based metal-organic framework [Zr6(μ3-O)4(μ3-OH)4(OH)4(H2O)4(TB)2].2DMF.2H2O (UPC-50) was synthesized based on 3,3',5,5'-tetra(4-carboxyphenyl)bimesityl (H4TB) with steric hindrance effect under hydrothermal conditions. UPC-50 features a three-dimensional frame with two-dimensional channels and high hydrothermal and chemical stability. The Zr-OH bond in Zr6 cluster enables UPC-50 excellent removal c...
