T.;Duong, Hai M.;Lee, Poh Seng;Zhao, Xiaoxu;Koh, Ming Joo;Yan, Ning;Loh, Kian Ping research published 《 Addressing the quantitative conversion bottleneck in single-atom catalysis》, the research content is summarized as follows. Single-atom catalysts (SACs) offer many advantages, such as atom economy and high chemoselectivity; however, their practical application in liquid-phase heterogeneous catalysis is hampered by the productivity bottleneck as well as catalyst leaching. Flow chem. is a well-established method to increase the conversion rate of catalytic processes, however, SAC-catalyzed flow chem. in packed-bed type flow reactor is disadvantaged by low turnover number and poor stability. In this study, we demonstrate the use of fuel cell-type flow stacks enabled exceptionally high quant. conversion in single atom-catalyzed reactions, as exemplified by the use of Pt SAC-on-MoS2/graphite felt catalysts incorporated in flow cell. A turnover frequency of approx. 8000 h-1 that corresponds to an aniline productivity of 5.8 g h-1 is achieved with a bench-top flow module (nominal reservoir volume of 1 cm3), with a Pt1-MoS2 catalyst loading of 1.5 g (3.2 mg of Pt). X-ray absorption fine structure spectroscopy combined with d. functional theory calculations provide insights into stability and reactivity of single atom Pt supported in a pyramidal fashion on MoS2. Our study highlights the quant. conversion bottleneck in SAC-mediated fine chems. production can be overcome using flow chem.

Herein, the chem. optimization of initial hit, 1-phenyl-3-(thiophen-2-yl)urea, which resulted in the identification of SMU-C80 I (V) (EC50 = 31.02 ± 1.01 nM) as a TLR2-specific agonist with a 370-fold improvement in bioactivity was presented. Mechanistic studies revealed that SMU-C80 (V), through TLR1/2, recruits the adaptor protein MyD88 and triggers the NF-κB pathway to release cytokines such as TNF-α and IL-1βfrom human, but not murine, cells. To the best of the knowledge, it is the first species-specific TLR1/2 agonist reported until now. Moreover, SMU-C80 (V) increased the percentage of T, B, and NK cells ex vivo and activated the immune cells, which suppressed cancer cell growth in vitro. In summary, a highly efficient and specific human TLR1/2 agonist II (R1 = H, Et, iso-Pr, phenylethyl, etc.; R2 = 4-fluorophenyl, naphth-1-yl, 4-bromonaphth-1-yl, etc.; n = 1-3; Y = O, S), III (R3 = H, phenyl) and IV (X = CH, N) that acts through the MyD88 and NF-κB pathway, facilitating cytokine release and the simultaneous activation of immune cells that in turn affects the apoptosis of cancer cells was obtained.

High-performance membranes exceeding the conventional permeability-selectivity upper bound are attractive for advanced gas separations In the context microporous polymers have gained increasing attention owing to their exceptional permeability, which, however, demonstrate a moderate selectivity unfavorable for separating similarly sized gas mixtures Here we report an approach to designing polymeric mol. sieve membranes via multi-covalent-crosslinking of blended bromomethyl polymer of intrinsic microporosity and Troger’s base, enabling simultaneously high permeability and selectivity. Ultra-selective gas separation is achieved via adjusting reaction temperature, reaction time and the oxygen concentration with occurrences of polymer chain scission, rearrangement and thermal oxidative crosslinking reaction. Upon a thermal treatment at 300°C for 5 h, membranes exhibit an O2/N2, CO2/CH4 and H2/CH4 selectivity as high as 11.1, 154.5 and 813.6, resp., transcending the state-of-art upper bounds. The design strategy represents a generalizable approach to creating mol.-sieving polymer membranes with enormous potentials for high-performance separation processes.

Chen, Xiuling;Wu, Lei;Yang, Huimin;Qin, Yong;Ma, Xiaohua;Li, Nanwen research published 《 Tailoring the Microporosity of Polymers of Intrinsic Microporosity for Advanced Gas Separation by Atomic Layer Deposition》, the research content is summarized as follows. Tailoring the microporosity of intrinsically microporous polymers at the at. level is one of the biggest challenges in achieving high-performance polymeric gas separation membranes. In this study, for the first time, the Al2O3 at. layer deposition (ALD) technique was used to modify the microporosity of a typical polymer of intrinsic microporosity (PIM-1) at the at. level. PIM-1 with six ALD cycles (PIM-1-Al2O3-6) exhibited simultaneous high thermal, mech., pure- and mixed-gas separation, and anti-aging properties. The O2/N2, H2/N2, and H2/CH4 separation performances were adequate above the latest trade-off lines. PIM-1-Al2O3-6 showed CO2 and O2 permeabilities of 624 and 188 Barrer, combined with CO2/CH4 and O2/N2 selectivities of 56.2 and 8.8, resp. This significantly enhanced performance was attributed to the strong size sieving effect induced by the Al2O3 deposition.

Organic materials with adjustable structures and wide sources are expected to become potential candidates for com. cathodes of lithium-ion batteries (LIBs). However, most organic materials have unstable structures, poor conductivity, and are easily soluble in electrolytes, resulting in unsatisfactory lithium storage performance. Covalent-organic frameworks have attracted extensive attention due to their stable frame structures, adjustable pore structures and functionalized official groups. Herein, a fluorinated covalent triazine framework (FCTF) is synthesized by a simple ion-thermal method. Compared with the fluorine-free covalent triazine frameworks (CTFs), the introduction of fluorine improves the lithium storage performance of CTF. When used as a cathode for lithium ion batteries, FCTF can retain a reversible capacity of 125.6 mA h g-1 after 200 cycles at a c.d. of 100 mA g-1. Besides, it also delivers 106.3 mA h g-1 after 400 cycles at a c.d. of 200 mA g-1 with 0.03% decrease per cycle (from 40 to 400 cycles).

To expand the processing window of phthalonitrile resins, a novel self-catalyzed amino-epoxy 4-aminophenoxy phthalonitrile-resorcinol diglycidyl ether phthalonitrile (APRE-PN) resin was prepared via a two-step method of reacting amino and epoxy groups at a low temperature and then reacting nitrile with nitrile groups at a high temperature The amine-epoxy, epoxy-nitrile, and nitrile-nitrile reactions were confirmed by Fourier-transform IR spectroscopy and differential scanning calorimetry, and the probable polymerization mechanism was elucidated. The significant decrease in the m.p. of the proposed APRE-PN prepolymers dramatically expands the processing window (173°C) for an entire class of phthalonitrile matrixes. The APRE-PN resin exhibits excellent thermal stability and dynamic mech. properties owing to the presence of triazine, phthalocyanine, and oxazoline structures.

Chen, Wenbo;Zhang, Zhenguo;Yang, Cancan;Liu, Jing;Shen, Hongcheng;Yang, Kai;Wang, Zhe research published 《 PIM-based mixed-matrix membranes containing MOF-801/ionic liquid nanocomposites for enhanced CO2 separation performance》, the research content is summarized as follows. In this work, we fabricated PIM-based mixed matrix membranes (MMMs) containing MOF-801/ionic liquid nanocomposites to enhance CO2 separation performance of pure polymer membranes. All membranes and MOF-801/ionic liquid nanocomposites were prepared by solution casting method and wet impregnation, resp. The samples were analyzed by SEM, XRD, FTIR, TGA and Nitrogen adsorption-desorption measurements. The nanocomposites are composed of metal-organic framework (MOF) MOF-801 and ionic liquid (IL) adsorption capacity. MOF-801 can well control the dispersion of IL in the polymer matrix, which is conducive to exposing more active sites in the nanocomposites to improve the CO2 adsorption selectivity of MOF-801/ionic liquid nanocomposites. At the same time, the porous structure of nanocomposites also enhances the gas adsorption and diffusion, thereby improving the gas separation performance. Compared with pure PIM-1 membranes, the CO2 permeability and CO2/N2 selectivity of IL@MOF/PIM-5% MMMs was increased by 129% and 45% (CO2 = 9420 Barrer, CO2/N2 = 29), resp. Compared with MOF-801/PIM-1 MMMs, the permeability of CO2 decreased slightly but the selectivity of CO2/N2 increased from 27 to 29. The aging test showed that the CO2 permeability of MMMs could remain above 70% after 90 days. The anti-plasticization performance of MMMs has also been significantly improved. The CO2 separation performance of IL@MOF/PIM-5% MMMs significantly exceeded the 2008 Robeson upper bound, showing excellent gas separation performance and working stability.

Chen, Shu-Jie;Chen, Guo-Shu;Deng, Tao;Li, Jia-Hui;He, Zhi-Qing;Liu, Li-Shan;Ren, Hai;Liu, Yun-Lin research published 《 1,2-Dicarbofunctionalization of Trifluoromethyl Alkenes with Pyridinium Salts via a Cycloaddition/Visible-Light-Enabled Fragmentation Cascade》, the research content is summarized as follows. Although trifluoromethyl alkenes have great synthetic potential, their 1,2-difunctionalization has been a challenge. In this Letter, authors disclose the first 1,2-dicarbofunctionalization of trifluoromethyl alkenes with pyridinium salts via a cascade process involving a base-promoted [3+2] cycloaddition followed by a visible-light-mediated Norrish-type-II fragmentation. This protocol allows for the formation of pyridines bearing a trifluoromethyl-substituted quaternary center in moderate to excellent yields under mild conditions.
