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, Qiang;Su, Yu-Xuan;Sun, Wei;Hu, Meng-Yang;Wang, Wei-Na;Zhu, Shou-Fei research published 《 Iron-Catalyzed Vinylzincation of Terminal Alkynes》, the research content is summarized as follows. Organozinc reagents are among the most commonly used organometallic reagents in modern synthetic chem., and multifunctionalized organozinc reagents can be synthesized from structurally simple, readily available ones by alkyne carbozincation. However, this method suffers from poor tolerance for terminal alkynes, and transformation of the newly introduced organic groups is difficult, which limits its applications. Herein, the authors report a method for vinylzincation of terminal alkynes catalyzed by newly developed Fe catalysts bearing 1,10-phenanthroline-imine ligands. This method provides efficient access to novel organozinc reagents with a diverse array of structures and functional groups from readily available vinylzinc reagents and terminal alkynes. The method features excellent functional group tolerance (tolerated functional groups include amino, amide, cyano, ester, hydroxyl, sulfonyl, acetal, phosphono, pyridyl), a good substrate scope (suitable terminal alkynes include aryl, alkenyl, and alkyl acetylenes bearing various functional groups), and high chemoselectivity, regioselectivity, and stereoselectivity. The method could significantly improve the synthetic efficiency of various important bioactive mols., including vitamin A. Mechanistic studies indicate that the new Fe-1,10-phenanthroline-imine catalysts developed in this study has an extremely crowded reaction pocket, which promotes efficient transfer of the vinyl group to the alkynes, disfavors substitution reactions between the Zn reagent and the terminal C-H bond of the alkynes, and prevents the further reactions of the products. The authors’ findings show that Fe catalysts can be superior to other metal catalysts in terms of activity, chemoselectivity, regioselectivity, and stereoselectivity when suitable ligands were used.

Huang, Qiang;Wang, Wei-Na;Zhu, Shou-Fei research published 《 Iron-Catalyzed Alkylzincation of Terminal Alkynes》, the research content is summarized as follows. Although carbozincation of terminal alkynes is a promising method for the synthesis of alkenylzinc reagents, many challenges, especially the chemo-, regio-, and stereoselectivity, remain to be addressed. The authors herein report an operationally simple, mild method for Fe-catalyzed alkylzincation of terminal alkynes to produce a diverse array of alkenylzinc compounds in high yields with high anti-Markovnikov selectivity and high cis stereoselectivity. Using this method, the authors realized a cis alkylzincation of terminal alkynes, and the method has a wide substrate scope (being suitable for aryl, alkenyl, alkyl, and heteroatom-substituted acetylenes) and good functional group tolerance. Because the C(sp²)-Zn bonds of the products can be readily transformed, the method provides a competitive alternative to traditional methods for the selective synthesis of trisubstituted olefins. The Fe catalyst developed in this study exhibited irreplaceable reactivity in alkyne alkylzincation.

Huang, Menghui;Wang, Zhenggong;Lu, Kuan;Fang, Wangxi;Bi, Xiangyu;Zhang, Yatao;Jin, Jian research published 《 In-situ generation of polymer molecular sieves in polymer membranes for highly selective gas separation》, the research content is summarized as follows. Mol. sieve materials (MSMs) are regarded as ideal fillers for the fabrication of mixed matrix membranes (MMMs). However, the preparation of MSMs-based MMMs usually involves phys. mixing of insoluble filler and polymer matrix, which inevitably leads to filler agglomeration and two-phase incompatibility especially for high filler loading. Herein, we report a new strategy to construct MMMs through generating polymer mol. sieve (PMS) fillers in-situ in a thermally stable polymer matrix by post heating treatment. The in-situ generated PMS-based MMMs (i-PMS MMMs) possess greatly improved interfacial compatibility between matrix and filler and the effective loading content of PMS filler can reach as high as 70 wt%. The mol. sieving property of PMS endows the i-PMS MMMs with high gas selectivity of 183.0 for H₂/CH₄ and 128.9 for H₂/N₂, approaching or exceeding the state-of-the-art 2015 upper bound.

Huang, Menghui;Lu, Kuan;Wang, Zhenggong;Bi, Xiangyu;Zhang, Yatao;Jin, Jian research published 《 Thermally Cross-Linked Amidoxime-Functionalized Polymers of Intrinsic Microporosity Membranes for Highly Selective Hydrogen Separation》, the research content is summarized as follows. Hydrogen is a vital and clean energy source, and it is of great significance to achieve efficient separation and purification of hydrogen. In this study, highly selective hydrogen separation was achieved by thermal crosslinking of amidoxime-functionalized polymers of intrinsic microporosity (AOPIM-1) membranes under an argon atm., where a two-step self-crosslinking reaction occurred among the amidoxime groups on the polymer chains by forming oxadiazole rings and triazine rings. The crosslinking reaction was systematically verified by ¹³C solid-state NMR, attenuated total reflection IR spectroscopy, and X-ray photoelectron spectrometry. Thanks to the controllable crosslinking reaction, not only are the gas transport channels finely tailored, but also the backbone structure is effectively retained. The resulting membranes exhibited remarkable mol. sieving behavior. The selectivities of H₂/CO₂, H₂/N₂, and H₂/CH₄ gas pairs are 16, 500, and 1000, resp., and the permeabilities of H₂, CO₂, N₂, and CH₄ are 300, 18.6, 0.6, and 0.3 Barrer, resp., far exceeding the state-of-the-art reported upper bound.

Huang, Lingqi;Luo, Zhiyong;Han, Wenjie;Zhang, Qi;Zhu, He;Zhu, Shiping research published 《 Direct transformation of ZIF-8 into hollow porous carbons and hollow carbon composites》, the research content is summarized as follows. Hollow porous carbons (HPCs) are a class of porous materials with advantages of high surface to volume ratio, large interior cavities, low d., and short diffusion length, which are promising in various applications. Direct carbonization of carbon precursors is the simplest and the most cost-effective method to prepare porous carbons, however, it often leads to non-hollow structures. Herein, we demonstrate the preparation of HPCs through a direct carbonization method with a two-step heating process of zeolitic imidazolate framework-8 (ZIF-8) and tetrafluoroterephthalonitrile (TFTPN). During the carbonization, ZIF-8 nanoparticles first react with TFTPN at low temperature to create polymer coatings on the surface, which are then converted into HPCs at elevated temperature The obtained HPCs show hierarchically porous structure with high sp. surface areas and pore volumes Addnl., this method has been adopted to fabricate Au@HPCs yolk-shell composites, exhibiting good catalytic performance in nitrobenzene reduction The developed synthesis strategy can enrich the toolbox for the preparation of novel HPCs and their composites.

Huang, Lingqi;Xiang, Yang;Luo, Mingwu;Zhang, Qi;Zhu, He;Shi, Kaiyuan;Zhu, Shiping research published 《 Hierarchically porous carbon with heteroatom doping for the application of Zn-ion capacitors》, the research content is summarized as follows. Zinc-ion capacitors (ZICs) are newly emerged hybrid devices consisting of battery-type anodes and capacitive-type cathodes, which are expected to meet high energy-power demands. The performance of ZICs is usually limited by the poor performance of porous carbon cathodes. In this work, heteroatom doped, hierarchically porous carbons were developed using a straightforward and scalable one-step method. The sp. surface areas and pore size distributions could be tailored by adjusting the precursor ratio and their effects on the electrochem. performance were investigated. The fabricated ZICs showed the highest capacity of 168.4 mAh g^-1 with an energy d. of 131.9 Wh kg^-1 at 0.5 A g^-1. The highest power d. of 30.8 kW kg^-1 could be achieved at 40 A g-1, allowing a fast complete discharging of a ZIC device in 6.6 s. Furthermore, the cycling stability of the device was investigated, registering nearly 100% capacity retention and almost 100% Coulombic efficiency after 12,000 cycles at 10 A g^-1. The morphol. and impedance tests measured at different charge and discharge conditions shed some light on the mechanism of the hybrid capacitive behavior. The proposed carbon cathodes offer great potential for ZICs in energy storage applications.

In this work, a series of hydrolyzed polymers of intrinsic microporosity (PIMs) membranes were successfully synthesized under alk. conditions. Positron annihilation lifetime measurement is employed to analyze the pore structure of the hydrolyzed PIMs. In the original PIM-1, there are two kinds of pores, i.e. micropores with radius of 4.32 Å and ultramicropores with radius of 2.58 Å. The size of all the pores shows a continuous decrease with increasing hydrolysis time, which is confirmed by the reduced chain-to-chain spacing in the hydrolyzed PIMs measured by X-ray diffraction. Meanwhile, the fractional free volume also shows decrease after the hydrolysis process, while the relative number of ultramicropores increases. Benefiting from the smaller pore size in the hydrolyzed PIMs membrane, the gas mols. with smaller size (such as CO₂) can be separated more efficiently. The selectivity of CO₂/CH₄ of hydrolyzed PIMs reaches up to 30.05 with a relatively high CO₂ permeability of 140.58 Barrer, which exceeds the Robeson’s 1991 upper bound. Our results indicate that the hydrolyzed polymers of intrinsic microporosity membranes are promising candidates for gas separation membrane in the future.

Hu, Meng-Ke;Wang, Ning;Ma, Dong-Dong;Zhu, Qi-Long research published 《 Surveying the electrocatalytic CO₂-to-CO activity of heterogenized metallomacrocycles via accurate clipping at the molecular level》, the research content is summarized as follows. Heterogenized phthalocyanine-based mol. catalysts are the ideal electrocatalytic platforms for CO₂ reduction reaction (CO₂RR) because of their well-defined structures and potential properties. In addition to the pursuit of catalytic performances at industrial potentials, it is equally important to explore exptl. rules and design considerations behind activity and selectivity. Herein, we successfully developed a series of nickel phthalocyanines (NiPcs) with different alkyl chains immobilized on multi-walled carbon nanotubes (CNT) to unveil the structure-performance relationship for electrocatalytic CO₂RR in neutral electrolyte. Interestingly, a volcano-type trend was found between the activity for CO₂-to-CO conversion and alkyl chain lengths of NiPcs on CNT. Exptl. results further indicate that their electrocatalytic CO₂RR activities are highly related to the mol. dispersion and the heterointerfacial charge transfer capability adjusted by the alkyl chains. Particularly, the optimized electrocatalyst via accurate clipping at the mol. level exhibits an ultrahigh activity with Faradaic efficiency of CO up to 99.52%.
