    查看更多>>摘要：HpnG plays a crucial role in the production of ribosylhopane,a key intermediate in the biosynthesis of bacteriohopanepolyol.De-spite early extensive studies,the precise function of HpnG has remained elusive.Here,we report functional characterization of HpnG as a purine nucleoside phosphorylase,which converts adenosylhopane to phosphoribosylhopane in the presence of phos-phate.HpnG demonstrates broad substrate specificity and impressive stability,making it a valuable enzymatic tool for applications in nucleoside processing and related biotechnology.

    Multicolor Anti-counterfeiting Strategy and Synchronous High Capacity Storage Based on Acidochromic Organic Fluorescent Materials

    查看更多>>摘要：Many industries are plagued by economic losses and product failures caused by counterfeit goods.Therefore,advanced an-ti-counterfeiting techniques are continuously needed.In this study,we constructed a series of acid-base sensitive cyclic chalcone dyes A-F by modifying different electron-donating groups.Differences in acid sensitivity of different structures are well rationalised by NMR and theoretical calculations.Aniline is difficult to protonate than fatty amines,so there is a difference in fluorescence.Hiding and anti-counterfeiting of information is achieved by this phenomenon.Powder X and Y are the anti-counterfeit fluorescent powder con-taining montmorillonite and cyclic chalcone,which have orange fluorescence and the very similar appearance.However,under the in-fluence of acid the Powder X containing triphenylamine modified cyclic chalcone shows red shifted fluorescence and Powder Y con-taining morpholino and diethylamino groups modified cyclic chalcone shows blue shifted fluorescence.Therefore,the an-ti-counterfeiting strategy based on cyclic chaicone is not only limited to UV-irradiated fluorescence development,but also has more colorization and pattern variations with the aid of acid developer.Data encryption and decryption of numbers,English alphabets and Chinese characters have been realized using A—F,which have great potential for practical applications.

    Rational Designing MxSy@C(M=Ni,Co,Zn,Cu,Mn)Composites with Controlled Polysuifides Shuttling Behaviors towards Advanced Stable Room Temperature Na-S Batteries

    查看更多>>摘要：Room-temperature sodium-sulfur(RT-Na/S)batteries display attractive potential in large-scale energy-storage,but their practical ap-plication was still restricted by the serious dissolution of polysulfides.Herein,supported by the constructing of interface engineering,the metal sulfide-carbon nanocomposite can be prepared with considerable electrochemical properties.Utilizing the double-helix structure of carrageenan-metal hydrogels as precursors,in-situ metal sulfide(MxSy)nanostructure/3D carbon aerogels(3D CAs)can be successfully constructed.Importantly,with the assistance of the vulcanization process,3D carbon architecture was maintained in the composites and acted as a skeleton to optimize their structural stability.As the cathode of RT-Na/S batteries,ZnS/S@C and NiS2/S@C delivered an excellent cycling stability and rate performance(179.8 mAh·g-1 at 20 A·g-1 after 10000 cycling for ZnS/S@C,220.3 mAh·g-1 at 10 A·g-1 after 3000 cycling for NiS2/S@C).The detailed investigation of mechanism revealed that the powerful adsorption for Na2S4 originated from 3D metal sulfide-carbon structure.The well-designed architecture of sulfide-carbon composites servers as an electrocatalyst to alleviate the shuttle effect of polysulfides,resulting in the long-term electrochemical stability.Given this,the work is expected to provide promising insights for designing advanced cathode materials for RT-Na/S batteries.

    Gradual or Hysteretic Transition:Anion Effects on Cobalt(Ⅱ)Spin Crossover Complexes

    查看更多>>摘要：To better understand the impact of different anions on the structures and SCO properties of the CoⅡ SCO complexes,six new complex-es[Co(terpy-CH2OH)2]A2·sol(terpy-CH2OH=4'-(hydroxymethyl)-2,2';6',2"-terpyridine,A=Br-(1,sol=1.5H2O),I-(2),N3(3,sol=2H2O),H3BCN-(4),OTf-(5),and TsO-(6,sol=4H2O·CH3CN),have been synthesized and characterized.All six compounds consist of mononuclear[Co(terpy-CH2OH)2]2+cations and charge-balancing anions that differ in size,shape,and hydrogen bonding capacity.Complexes 1,2,3,and 6 displayed incomplete gradual SCO transitions,whereas 4 and 5 exhibited abrupt hysteretic spin transitions with loops of 12 and 16 K(250.0-262.0 K for 4,and 370.0-386.0 K for 5,respectively),closely resembling our previously reported complexes with SCN-and SeCN-anions.The occurrence of the order-disorder transition of the CH2OH groups and their transition temperatures are determined by the size and hydrogen bonding capability of the anions.Remarkably,the transition temperatures of complexes with H3BCN-,SCN-,OTf-,and SeCN-anions exhibit an upward trend as the size and mass of the anions increase,as con-firmed through detailed single crystal structure analyses conducted in both high-spin and low-spin states for all four complexes.

    Radicals as Chiral Catalysts for Asymmetric Radical Cyclization Reactions

    Quan-Qing ZhaoMin GuJia-Rong Chen
    2412-2416页
    查看更多>>摘要：Due to the innate highly reactive properties and short life-time,organic free radicals can often serve as promoters or intermediates to engage in various radical transformations,which are often otherwise difficult to access by ionic pathway-based mechanisms.With the evolvement of radical chemistry,chiral radical catalyzed-transformations have recently emerged as an attractive and robust plat-form for synthesis of chiral molecules of interest.Herein,we highlight several creative and strategic advances in chiral radical catalyst design,cyclization reaction achievements,and future challenges.
