An rht-type metal-organic framework (MOF) prepared from M(2)(carboxylate)(4) (M = Cu, Co) paddlewheel clusters and a flexible C(3)-symmetric hexacarboxylate ligand with acylamide groups exhibits larger CO(2) uptake, an enhanced heat of adsorption, higher selectivity toward CO(2)/N(2) in comparison what was previously observed for analogous MOF alkyne groups.
The adsorptive separation of C2H2 and CO2 via porous materials is nontrivial due to the close similarities their boiling points kinetic diameters. In this work, we describe a new flexible coordination polymer (PCP) [Mn(bdc)(dpe)] (H2bdc = 1,4-benzenedicarboxylic acid, dpe 1,2-di(4-pyridyl)ethylene) having zero-dimensional pores, which shows an adsorbate discriminatory gate effect. compound opening type abrupt adsorption for but not CO2, leading appreciable selective over at near ambient...
In comparison with the fast development of binary mixture separations, ternary separations are significantly more difficult and have rarely been realized by a single material. Herein, new strategy tuning gate-opening pressure flexible MOFs is developed to tackle such challenge. As demonstrated framework NTU-65, ethylene (C2 H4 ), acetylene H2 carbon dioxide (CO2 ) can be regulated temperature. Therefore, efficient sieving separation this was realized. Under optimized temperature, NTU-65...
Two series of lanthanide metal–organic frameworks (Ln-MOFs) from two structurally related flexible carboxylate-based ligands were solvothermally synthesized. H3L2 with additional −CH2− group provides more flexibility and different coordination modes conformations compared H3L1. As a result, 2-Ln MOFs are modulated two-dimensional kgd 1-Ln to three-dimensional rtl topological further achieve enhanced chemical stability. The Eu- Tb-MOFs exhibit strong fluorescent emission at the solid state...
Enantioselective cross-electrophile reactions remain a challenging subject in metal catalysis, and with respect to data, studies have mainly focused on stereoconvergent of racemic alkyl electrophiles. Here, we report an enantioselective aryl-alkenylation reaction unactivated alkenes. This method provides access number biologically important chiral molecules such as dihydrobenzofurans, indolines, indanes. The incorporated alkenyl group is suitable for further that can lead increase molecular...
Covalent organic framework (COF) membranes used for selective removal of CO2 were believed as an efficient and low-cost solution to energy environmental sustainability. In this study, the amide modified COF nanosheet cluster with a 2D structure was facilely prepared through solid reaction, exhibiting good adsorption-based selectivity (223 at 273 K 90 298 K) toward N2. Remarkably, mixed matrix membrane (MMM) that consists lesser amount filler (1 wt %) shows promising CO2/N2 gas (∼64)....
Thermoelectric materials and their devices can realize the solid-state energy conversion between thermal electrical energy, therefore serving as a promising alternative to conventional fossil fuels for supply.
Energy-efficient separation of propylene (C3H6)/propane (C3H8) is in high demand for the chemical industry. However, this process challenging due to imperceptible difference molecular sizes these gases. Here, we report a continuous water nanotube dedicatedly confined Cu10O13-based metal-organic framework (MOF) that can exclusively adsorb C3H6 over C3H8 with record-high selectivity 1570 (at 1 bar and 298 K) among all porous materials. Such originates from new mechanism initial expansion...
Abstract Ethylene (C 2 H 4 ) purification from multicomponent mixtures by physical adsorption presents a great challenge in the chemical industry. This work successfully uses postsynthetic method of crystal transformation boiling alkaline solution to synthesize trap‐and‐flow channel (namely NTU‐67), flow which provides an effective shape‐ and size‐dependent sieving path for linear molecules such as acetylene carbon dioxide (CO ), while adjacent possesses customized space efficient molecular...
Soft nanoporous crystals with structural dynamics are among the most exciting recently discovered materials. However, designing or controlling a porous system delicate softness that can recognize similar gas pairs, particularly for promoted ability at increased temperature, remains challenge. Here, we report soft crystal (NTU-68) one-dimensional (1D) channel expands and contracts delicately around 4 Å elevated temperature. The completely different adsorption processes of propane (C3H8:...
Abstract A new porous coordination polymer, ([La(BTB)H 2 O]·solvent ( 1 ⊃guest)), is synthesized. Gas adsorption, ideal adsorbed solution theory (IAST) and breakthrough experiments of it exhibits high CH 4 separation capability toward CO C2 hydrocarbons at 273 K. In addition, this also shows good water chemical stability, in particular, stable pH = 14 100 °C, which unprecedented for carboxylate‐based polymers. Furthermore, the effective adsorption site revealed by using an situ diffuse...
Porous coordination polymers (PCPs), constructed from organic linkers and metal ions, can provide special pore environments for selective CO2 capture. Although many PCPs have been reported, a rational design identifying that adsorb molecules with low binding energy, high separation ability chemical stability remains great challenge. Here, we propose validate, experimentally computationally, new PCP, [La(BTN)DMF]·guest (PCP-1⊃guest), has large aromatic surface energy four-gas mixtures...
An amide-inserted metal-organic framework (NJU-Bai3) presents high storage and selectivity toward CO(2) combines these two interesting characters which strongly support our expectation that amide groups can significantly enhance the binding ability of MOFs.
Porous coordination polymers (PCPs), constructed by bridging the metals or clusters and organic linkers, can provide a functional pore environment for gas storage separation. But rational design identifying PCPs with high efficiency low energy cost remains challenge. Here, we demonstrate new PCP, [(Cu4Cl)(BTBA)8·(CH3)2NH2)·(H2O)12]·xGuest (PCP-33⊃guest), which shows potential purification of natural gas, separation C2H2/CO2 mixtures, selective removal C2H2 from C2H2/C2H4 mixtures at ambient...
The prevalence of the condensed phase, interpenetration, and fragility mesoporous coordination polymers (meso-PCPs) featuring dense open metal sites (OMSs) place strict limitations on their preparation, as revealed by experimental theoretical reticular chemistry investigations. Herein, we propose a rational design stabilized high-porosity meso-PCPs, employing low-symmetry ligand in combination with shortest linker, formic acid. resulting dimeric clusters (PCP-31 PCP-32) exhibit high surface...

We demonstrate a new approach to superhydrophobic porous coordination polymers by incorporating an anisotropic crystal morphology featuring predominant surface that is highly corrugated and terminated aromatic hydrocarbon moieties. The resulting low-energy provides particularly promising hydrophobic properties without the need for postsynthetic modifications or processing would block porosity of framework. Consequently, organic molecules water vapor are able penetrate be densely accommodated...
