Huang, Shi-sheng;Zhu, Bin-bing;Wang, Kai-hua;Yu, Mo;Wang, Zi-wen;Li, Yongqiang;Liu, Yu-xiu;Zhang, Peng-li;Li, Shou-jun;Li, Ya-ling;Liu, Ai-ling;Wang, Qing-min research published 《 Design, synthesis, and insecticidal and fungicidal activities of quaternary ammonium salt derivatives of a triazolyphenyl isoxazoline insecticide》, the research content is summarized as follows. Insect pests seriously decrease the yield and quality of agricultural crops. Resistance to commonly used insecticides is increasingly undermining their effectiveness, and therefore the development of agents with novel modes of action is desirable. Isoxazolines are a new class of insecticides that act on γ-aminobutyric acid (GABA) gated chloride channels. In this work, we used the highly active 4-triazolyphenyl isoxazoline DP-9 as a parent structure to design and synthesize a series of quaternary ammonium salt (QAS) derivatives, and we systematically evaluated their insecticidal and antifungal activities. RESULTS : Many of the synthesized QASs exhibit insecticidal activities equivalent to or higher than that of DP-9. In particular, compounds I-31 (93%, 0.00005 mg/L) and I-34 (80%, 0.00001 mg/L) showed insecticidal activities against diamondback moth larvae that were 2-10 times higher than those of fluralaner (70%, 0.0001 mg/L) and DP-9 (80%, 0.0001 mg/L), in addition to showing excellent activities against oriental armyworm, fall armyworm, cotton bollworm, corn borer, and mosquito larvae. Furthermore, all of the synthesized compounds also showed broad-spectrum fungicidal activities. The insecticidal activities of QAS derivatives of DP-9 were the same as or better than the activity of DP-9. Compounds I-31 and I-34 showed better insecticidal activities against diamondback moth larvae than fluralaner and DP-9, and thus are promising new candidates for insecticide research.

Huang, Tong;Zhang, Junfeng;Pei, Yabiao;Liu, Xin;Xue, Jiandang;Jiang, Haifei;Qiu, Xiaoyu;Yin, Yan;Wu, Hong;Jiang, Zhongyi;Guiver, Michael D. research published 《 Mechanically robust microporous anion exchange membranes with efficient anion conduction for fuel cells》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) present an attractive opportunity for developing new types of anion exchange membranes (AEMs) for fuel cell featuring charged subnanometer-sized micropores. But challenges exist to make mech. robust PIM AEMs due to their high chain rigidity. Imparting more flexibility improves mech. properties but sacrifices microporosity. Here, a mech. robust and highly anion conductive PIM AEM (QPIM-1) fabricated by facile animation and quaternization of PIM-1 membrane is reported, and its structure-property relationships are investigated, especially focusing on the microporous structure. High mol. weight alleviates brittleness, as QPIM-1 AEM shows comparable mech. properties to conventional AEMs, quaternized poly(2,6-dimethyl-1,4-phenylene oxide) (QPPO), at a membrane thickness down to ∼35μm and a high ion exchange capacity (IEC) up to ∼2.1 mmol g-1. The micropores situated among the rigid and contorted polymer chains evolve into water/ion conduction channels when the membrane is hydrated. This results in improved morphol. over dense polymeric AEMs by less hindered ion pathways. QPIM-1 AEMs exhibit superior ion conduction efficiency, which is 2.6-5.3 times that of dense QPPO AEM at similar ion exchange capacities (IECs). A high hydroxide ion conductivity of 57 mS cm^-1 at 20°C is obtained, which is among the highest reported anion conductive PIM-based AEMs. Even though the AEMs are microporous, only slight H₂ permeation is observed when hydrated and at high open circuit voltage (OCV) of a single fuel cell.

Huang, Zhaolai;Li, Jiaqi;Zhang, Mengxiao;Feng, Weilin;Fang, Chuanjie;Zhu, Liping research published 《 Improving aging resistance of PIM -1 thin films by nano-TiO₂ filler used for robust solvent permeation》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) are promising materials for membrane separation because their special rigid and contorted structures contribute to high permeability. However, their chain rearrangement to fill excessive free volume makes the permeability stability a tough challenge. In this work, we report on a new use of rutile nano-TiO₂ to mitigate the phys. aging of PIM-1 (a typical PIM) nanofilms for stable permeability by mixing matrix. It was shown that the PIM-1 membrane incorporated with nano-TiO₂ displayed remarkably higher aging resistance with a lower swelling degree in long-term ethanol soaking, having more stable ethanol permeance with only a 5% decrease after 35 days, lower than 25% of the pure one. The mechanism of anti-aging was revealed by mol. simulation, thermal, tensile mech., and dynamic mech. anal. It was found that nano-TiO₂ had good compatibility with PIM-1 due to strong coordination interaction, making its uniform dispersion in polymer. Addnl. solvent permeation channels were also created to increase solvent permeance without compromising solute rejection. Due to the reliable interaction of nano-TiO₂, which makes particles serve as phys. crosslinking points, the movement of PIM-1 chains was limited partially to mitigate aging, enabling PIM-1-based membranes to have robust solvent permeation.

A facile synthesis of quinoxalines by the cyclocondensation of substituted phenacyl bromides with o-pheneylenediamines using silica-supported dodecatungstophosphoric acid (DTP/SiO₂) as a recyclable heterogeneous catalyst is unveiled in this research work. This method is practicable due to environmentally benign, easy workup, high yield, less reaction time, low cost, mild reaction condition, and recyclable heterogeneous catalyst.
