Zn(tbip) (H₂tbip= 5-tert-Butyl Isophthalic Acid):  A Highly Stable Guest-Free Microporous Metal Organic Framework with Unique Gas Separation Capability

Abstract

A novel guest-free metal organic framework (GFMMOF) is synthesized and structurally characterized. It contains one-dimensional close-packed open channels with a pore diameter of 4.5 A. It demonstrates a remarkable thermal stability, a unique ability to separate methanol from dimethyl ether or water, and is among the microporous MOFs having the highest adsorbed hydrogen density (0.054 g/cm3 at 77 K and 1 atm).

“…The porosity, structure and functionality of the MOF can be tuned by varying the linkers (bridging ligands) and/or the metal centers. MOFs are promising materials for applications in gas adsorption 3,4 , separation 5 and catalysis 6,7,8 . By introducing catalytically active metal-connecting points or functional groups into the highly porous MOF structure, MOFs exhibit clear advantages in heterogeneous catalysis.…”

“…Coordination polymers (CPs) and metal-organic frameworks (MOFs) are well-known crystals constructed by an organic compound and a metal. Porous CPs (PCPs) and MOFs, in particular, are highly potential materials for gas storage, 22-24 ion exchange, 25-28 heterogeneous catalysis, 29-31 separation, 29,[32][33][34][35][36] and non-linear optics, 37-39 because of the nanospace separated from bulk space.Structure construction with a coordination bond plays a critical role in the formation of a complicated structure and the introduction of functionality into the structure for basic research and industrial applications. In structure control, it is important to adjust the metal-ligand stoichiometry based on the number of coordination sites or the coordination environment.…”

OBGMX: A web‐based generator of GROMACS topologies for molecular and periodic systems using the universal force field

“…The set considered here includes the original series of Isoreticular MOFs, [16] Covalent Organic Frameworks, [17] Zeolitic Imidazolate Frameworks, [18,19] breathing MOFs [20][21][22] and the molecular sieve Zn-TBIP. [23] The starting configurations for the optimizations were taken as the X-ray structure indicated in the original papers. These configurations were replicated to have simulation cells capable of accommodating a cutoff of 17 Å , and subsequently optimized using the conjugate gradient method available in GRO-MACS.…”
