Cheng, Gong;Zhang, Anrui;Zhao, Zhiwei;Chai, Zimin;Hu, Baowei;Han, Bing;Ai, Yuejie;Wang, Xiangke research published 《 Extremely stable amidoxime functionalized covalent organic frameworks for uranium extraction from seawater with high efficiency and selectivity》, the research content is summarized as follows. Uranium extraction from seawater is of strategic significance for nuclear power generation. Amidoxime-based functional adsorbents play indispensable roles in the recovery of seawater uranium with high efficiency. Nevertheless, balancing the adsorption capacity and selectivity is challenging in the presence of complicated interfering ions especially vanadium. Herein, a polyarylether-based covalent organic framework functionalized with open-chain amidoxime (COF-HHTF-AO) was synthesized with remarkable chem. stability and excellent crystallinity. Impressively, the adsorption capacity of COF-HHTF-AO towards uranium in natural seawater reached up to 5.12 mg/g, which is 1.61 times higher than that for vanadium. Detailed computational calculations revealed that the higher selectivity for uranium over vanadium originated from the specific bonding nature and coordination pattern with amidoxime. Combining enhanced adsorption capacity, excellent selectivity and ultrahigh stability, COF-HHTF-AO serves as a promising adsorbent for uranium extraction from the natural seawater.

Choi, Sang-Kee;Lee, Youngjun;Yoon, Sang Eun;Choi, Hongseo;Kim, Jonghoon;Kim, Jong H.;Lee, Sanghee;Kim, Wook;Kim, Eunha research published 《 A tetrazine-fused aggregation induced emission luminogen for bioorthogonal fluorogenic bioprobe》, the research content is summarized as follows. Bioorthogonal fluorogenic probes allow spatiotemporally controlled mol. bioimaging with minimal perturbation of the native cellular environment. Due to favorable kinetics and reaction specificity in a physiol. environment, inverse electron-demand Diels – Alder reaction (iEDDA) for bioorthogonal fluorogenic bioimaging has gained immense attention in scientific field; however, the technique still needs to washout excess trans-cyclooctene labels, thereby reducing the robustness and exptl. convenience. In the present study, we report tetrazine-modified aggregation-induced emission luminogens for bioorthogonal fluorogenic bioimaging. We found that a unique mol. design strategy allowed incorporation of tetrazine on aggregation-induced emission luminogens with excellent fluorogenic properties. Moreover, tetrazine modification of aggregation-induced emission luminogens results in non-radiative decay, which induces fluorescence quenching. The systematic tunability of the emission wavelength of the fluorescent core skeleton allowed successful development of three different colorful fluorogenic tetrazine-fluorophores. Furthermore, an aggregate formation study and computational calculations revealed a synergistic fluorescent quenching effect between intramol. charge transfer and tetrazine-mediated non-radiative decay. The final simple conjugation between triphenylphosphonium and tetrazine-fluorophore enabled successful development of fluorogenic probes for spatiotemporally controlled bioorthogonal bioimaging of mitochondria in live cells with the iEDDA without washing the trans-cyclooctene label and tetrazine-fluorophore.

Contreras-Martinez, Jorge;Mohsenpour, Sajjad;Ameen, Ahmed W.;Budd, Peter M.;Garcia-Payo, Carmen;Khayet, Mohamed;Gorgojo, Patricia research published 《 High-Flux Thin Film Composite PIM-1 Membranes for Butanol Recovery: Experimental Study and Process Simulations》, the research content is summarized as follows. Thin film composite (TFC) membranes of the prototypical polymer of intrinsic microporosity (PIM-1) have been prepared by dip-coating on a highly porous electrospun polyvinylidene fluoride (PVDF) nanofibrous support. Prior to coating, the support was impregnated in a non-solvent to avoid the penetration of PIM-1 inside the PVDF network. Different non-solvents were considered and the results were compared with those of the dry support. When applied for the separation of n-butanol/water mixtures by pervaporation (PV), the developed membranes exhibited very high permeate fluxes, in the range of 16.1-35.4 kg m^-2 h^-1, with an acceptable n-butanol/water separation factor of about 8. The PV separation index (PSI) of the prepared membranes is around 115, which is among the highest PSI values that have been reported so far. Hybrid PV-distillation systems have been designed and modeled in Aspen HYSYS using Aspen Custom Modeler for setting up the PIM-1 TFC and com. PDMS membranes as a benchmark. The butanol recovery cost for the hybrid systems is compared with a conventional stand-alone distillation process used for n-butanol/water separation, and a 10% reduction in recovery cost was obtained.

Persulfides and polysulfides, collectively known as the sulfane sulfur pool along with hydrogen sulfide (H2S), play a central role in cellular physiol. and disease. Exogenously enhancing these species in cells is an emerging therapeutic paradigm for mitigating oxidative stress and inflammation that are associated with several diseases. In this study, we present a unique approach of using the cell′s own enzyme machinery coupled with an array of artificial substrates to enhance the cellular sulfane sulfur pool. We report the synthesis and validation of artificial/unnatural substrates specific for 3-mercaptopyruvate sulfurtransferase (3-MST), an important enzyme that contributes to sulfur trafficking in cells. We demonstrate that these artificial substrates generate persulfides in vitro as well as mediate sulfur transfer to low mol. weight thiols and to cysteine-containing proteins. A nearly 100-fold difference in the rates of H₂S production for the various substrates is observed supporting the tunability of persulfide generation by the 3-MST enzyme/artificial substrate system. Next, we show that the substrate 1a permeates cells and is selectively turned over by 3-MST to generate 3-MST-persulfide, which protects against reactive oxygen species-induced lethality. Lastly, in a mouse model, 1a is found to significantly mitigate neuroinflammation in the brain tissue. Together, the approach that we have developed allows for the on-demand generation of persulfides in vitro and in vivo using a range of shelf-stable, artificial substrates of 3-MST, while opening up possibilities of harnessing these mols. for therapeutic applications.

Butt, Tahreem Hafeez;Tamime, Rahma;Budd, Peter M.;Harrison, Wayne J.;Shamair, Zufishan;Khan, Asim Laeeq research published 《 Enhancing the organophilic separations with mixed matrix membranes of PIM-1 and bimetallic Zn/Co-ZIF filler》, the research content is summarized as follows. Novel mixed matrix membranes (MMMs) were fabricated by incorporating bimetallic Zn/Co-ZIF nanoparticles into the prototypical polymer of intrinsic microporosity (PIM-1). The morphol. and structural characteristics of Zn/Co-ZIF and ZIF-8 were analyzed with XRD, FTIR, BET and SEM. The characterization results showed that the Zn/Co-ZIF is isostructural to ZIF-8 occupying the same crystallog. sites, however, Zn/Co-ZIF has smaller BET surface area and lower pore volume than ZIF-8. The SEM images of fabricated MMMs demonstrated good dispersion and interaction of the filler in the polymer matrix, even at high loadings. The addition of hydrophobic nanoparticles enhanced the hydrophobicity of the MMMs, and relatively more for the Zn/Co-ZIF/PIM. The MMMs were analyzed for their separation performance of two binary mixtures made of ethanol/water and butanol/water comprising 5 wt% alc., via pervaporation. Flux and separation factor of both alcs. increased with filler loadings in both ZIF-8/PIM-1 and Zn/Co-ZIF/PIM-1 membranes, showing an anti-tradeoff effect which is more significant in Zn/Co-ZIF/PIM-1 membranes. Zn/Co-ZIF/PIM-20 wt% membranes showed 129% higher separation in comparison with pristine PIM-1 membranes. Moreover, not only did the Zn/Co-ZIF/PIM-1 membranes show a higher separation factor, but they also had a higher rate of increase with increased loadings, which was quasi-constant for ZIF-8/PIM-1 membranes. ZIF-8/PIM-1 at filler loading of 20 wt% showed the highest normalized flux of 139 kg.μm.m^-2.h^-1.

Caliskan, Esra;Shishatskiy, Sergey;Neumann, Silvio;Abetz, Volker;Filiz, Volkan research published 《 Investigation of the Side Chain Effect on Gas and Water Vapor Transport Properties of Anthracene-Maleimide Based Polymers of Intrinsic Microporosity》, the research content is summarized as follows. In the present work, a set of anthracene maleimide monomers with different aliphatic side groups obtained by Diels Alder reactions were used as precursors for a series of polymers of intrinsic microporosity (PIM) based homo- and copolymers that were successfully synthesized and characterized. Polymers with different sizes and shapes of aliphatic side groups were characterized by size-exclusion chromatog. (SEC), (NMR) ¹H-NMR, thermogravimetric (TG) anal. coupled with Fourier-Transform-IR (FTIR) spectroscopy (TG-FTIR) and d. measurements. The TG-FTIR measurement of the monomer-containing Me side group revealed that the maleimide group decomposes prior to the anthracene backbone. Thermal treatment of homopolymer methyl-100 thick film was conducted to establish retro-Diels Alder rearrangement of the homopolymer. Gas and water vapor transport properties of homopolymers and copolymers were investigated by time-lag measurements. Homopolymers with bulky side groups (i-propyl-100 and t-butyl-100) experienced a strong impact of these side groups in fractional free volume (FFV) and penetrant permeability, compared to the homopolymers with linear alkyl side chains. The effect of anthracene maleimide derivatives with a variety of aliphatic side groups on water vapor transport is discussed. The maleimide moiety increased the water affinity of the homopolymers. Phenyl-100 exhibited a high water solubility, which is related to a higher amount of aromatic rings in the polymer. Copolymers (methyl-50 and t-butyl-50) showed higher CO₂ and CH₄ permeability compared to PIM-1. In summary, the introduction of bulky substituents increased free volume and permeability while the maleimide moiety enhanced the water vapor affinity of the polymers.

MOF-based mixed-matrix membranes (MMMs) prepared using standard routes often exhibit poor adhesion between polymers and MOFs. Herein, we report an unprecedented systematic exploration on polymer functionalization as the key to achieving defect-free MMMs. As a case study, we explored computationally MMMs based on the combination of the prototypical UiO-66(Zr) MOF with polymer of intrinsic porosity-1 (PIM-1) functionalized with various groups including amidoxime, tetrazole, and N-((2-ethanolamino)ethyl)carboxamide. Distinctly, the amidoxime-derivative PIM-1/UiO-66(Zr) MMM was predicted to express the desired enhanced MOF/polymer interfacial interactions and thus subsequently prepared and evaluated exptl. Prominently, high-resolution transmission electron microscopy confirmed optimal adhesion between the two components in contrast to the nanometer-sized voids/defects shown by the pristine PIM-1/UiO-66(Zr) MMM. Notably, single-gas permeation measurements further corroborated the need of optimal MOF/polymer adhesion in order to effectively enable the MOF to play a role in the gas transport of the resulting MMM.

Chang, Siqi;Xie, Wei;Yao, Chan;Xu, Guangjuan;Zhang, Shuran;Xu, Yanhong research published 《 Preparation of covalent triazine frameworks with multiactive sites for efficient and reversible iodine capture》, the research content is summarized as follows. Covalent triazine skeletons (CTFs) are long-chain polymers with rigid hydrophobic aromatic skeletons and polar functional groups. Here, we selected three monomers to explore a series of stable CTFs (FCTFs, NCTFs, ClCTFs) with multiple active sites at 350 and 400°C resp., which can act as a porous platform for effective and reversible iodine capture. The iodine adsorption capacities of FCTF@350, NCTF@350, ClCTF@350, FCTF@400, NCTF@400 and ClCTF@400 are 285, 232, 231, 382, 372 and 340 wt%, resp. Among them, the iodine capture capacities of FCTFs and NCTFs are higher than those of ClCTFs, which suggested that the introduction of electron-rich F and pyridine N groups can indeed improve the iodine adsorption capacity of the polymers. In addition, at 50 bar and 323 K, the CO₂ capture capacity of FCTF@350, NCTF@350, ClCTF@350, FCTF@400, NCTF@400 and ClCTF@400 are 631.6, 539.2, 496.6, 876.6, 783.3, and 695.4 mg g^-1, resp.
