“…Metal–organic frameworks (MOFs) have been extensively studied for gas storage, − separation, − capture of hazardous chemical species, − catalysis, , conductivity, − luminescence sensing, − and lighting − applications because of their permanent porosity and ease of tunability with regards to their pore shape, size, and chemistry . The facile functionalization of MOFs makes them versatile and attractive materials for numerous applications.…”

Adsorptive separation by porous solids provides an energy-efficient alternative for the purification of important chemical species compared to energy-intensive distillations. Particularly, the separation of linear hexane isomers from its branched counterparts is crucial to produce premium grade gasoline with high research octane number (RON). Herein, we report the synthesis of a new, flexible zinc-based metal–organic framework, [Zn5(μ3-OH)2(adtb)2(H2O)5·5 DMA] (Zn-adtb), constructed from a butterfly shaped carboxylate linker with underlying (4,8)-connected scu topology capable of separating the C6 isomers nHEX, 3MP, and 23DMB. The sorbate–sorbent interactions and separation mechanisms were investigated and analyzed through in situ FTIR, solid state NMR measurements and computational modeling. These studies reveal that Zn-adtb discriminates the nHEX/3MP isomer pair through a kinetic separation mechanism and the nHEX/23DMB isomer pair through a molecular sieving mechanism. Column breakthrough measurements further demonstrate the efficient separation of linear nHEX from the mono- and dibranched isomers.

“…1,1,2,2-tetra(4carboxylbiphenyl)ethylene (H 4 TCBPE), a derivative of TPE, has been employed as a rigid organic ligand to construct luminescent MOFs. To date, some luminescent MOFs based on H 4 TCBPE have been reported, including Zr 6 (μ 3 -O) 4 (OH) 8 (tcbpe) 2 (H 2 O) 4 , 47 Zr-MOFs (PCN-94 and PCN-128W), 48 (DMA)[In (TCBPE)](solv), 49 and so on. However, the sensing ability of these TCBPE-MOFs has rarely been explored.…”

The misuse of organic pollutants such as nitrofuran antibiotics (NFAs) and 2,6-dichloro-4-nitroaniline (DCN) has become a hot topic of global concern, and developing rapid, efficient, and accurate techniques for detecting NFAs and pesticides in water is a major challenge. Here, we designed a novel leadbased anion 2D metal−organic framework (MOF){[(CH 3 ) 2 NH 2 ] 2 [Pb(TCBPE)-(H 2 O) 2 ]} n (F3) with interlocking structures, in which TCBPE stands for 1,1,2,2tetra(4-carboxylbiphenyl)ethylene. Powder X-ray diffraction and thermogravimetric analysis revealed that F3 has excellent chemical and solvent stability. It is worth noting that F3 has a grinding discoloration effect. The solvent-protected grinding approach achieved F3B with a high quantum yield (QY = 73.77%) and blue fluorescence, while the direct grinding method produced F3Y with a high quantum yield (QY = 37.27%) and yellow−green fluorescence. Importantly, F3B can detect NFAs in water rapidly and sensitively while remaining unaffected by other antibiotics. F3Y can identify DCN in water quickly and selectively while remaining unchanged by other pesticides. F3B demonstrated high selectivity and rapid response to NFAs at a limit of detection (LOD) as low as 0.26 μM, while F3Y indicated high selectivity and responded quickly to DCN in water at an LOD as low as 0.14 μM. The method was successfully applied to detect NFAs in actual water samples of the fish tanks and ponds as well as the pesticide DCN in soil samples. The recovery rates were 97.0−105.15% and 102.2− 106.48%, and the relative standard deviations were 0.63−1.45% and 0.29−1.69%, respectively. In addition, F3B and F3Y can be made into fluorescent test papers for the visual detection of NFAs and DCN, respectively. Combined with experiments and density functional theory calculations, the mechanism of fluorescence quenching of MOFs by target analytes was also revealed.

“…Due to their toxicity and reactivity, expensive safety measures are required to handle, store, and transport these gases safely, thereby placing their usage in synthetic chemistry under strict regulations [7] . Herein, we probed metal‐organic frameworks (MOFs), [8–33] specifically their reversible gas adsorption and catalytic activity, to carry out chemical reactions in organic solvents. Thus, we explored the dual role of MOFs as a catalyst and carrier of reagents on the example of reactive gases.…”

A Metal‐Organic Framework (MOF)‐Based Multifunctional Cargo Vehicle for Reactive‐Gas Delivery and Catalysis

The efficient delivery of reactive and toxic gaseous reagents to organic reactions was studied using metal‐organic frameworks (MOFs). The simultaneous cargo vehicle and catalytic capabilities of several MOFs were probed for the first time using the examples of aromatization, aminocarbonylation, and carbonylative Suzuki–Miyaura coupling reactions. These reactions highlight that MOFs can serve a dual role as a gas cargo vehicle and a catalyst, leading to product formation with yields similar to reactions employing pure gases. Furthermore, the MOFs can be recycled without sacrificing product yield, while simultaneously maintaining crystallinity. The reported findings were supported crystallographically and spectroscopically (e.g., diffuse reflectance infrared Fourier transform spectroscopy), foreshadowing a pathway for the development of multifunctional MOF‐based reagent‐catalyst cargo vessels for reactive gas reagents as an attractive alternative to the use of toxic pure gases or gas generators.
