    查看更多>>摘要:The hierarchical assemblies of precise nanoparticles(NPs)have created materials with emergent properties and functionalities.However,the complex assemblies remain unclear at a precise scale.Here,we show the hierarchical self-assembly of atomically precise gold nanoclusters(Au NCs)with molecular rotor-based ligands(MRL),featuring a double-layer surface.Compared to two other types of monolayer-protected(MLP)Au NCs,the significantly reduced surface density for MRL Au NCs profoundly influences their assembly behavior within the lattice.Furthermore the long length of rotor-based ligands and the rotational freedom of the phenyl-rings of rotor-based ligands also facilitate the assembly of NCs.Our works elucidate the hierarchical assembly on a precise scale,suggesting that the rotor-based ligand's strategy offers promising potential for designing well-defined and more complex structures in supercrystals.

    查看更多>>摘要:Representing the next-generation technology in lithium-ion batteries,lithium-sulfur(Li-S)batteries offer increased specific energy without relying on scarce metals like nickel and cobalt,but suffer from a low practical specific energy due to poor conductivity and a short lifespan due to the shuttle effect of polysulfides.Balancing the confinement of polysulfides and the transport of lithium ions requires highly elaborate modifiers for separators.Hollow multi-shelled structures(HoMS)show promise as hierarchical mesostructures for separators,offering multiple shell layers and internal cavities that effectively inhibit polysulfide shuttle.Thoughtful design of these structures is crucial to address these challenges effectively.In this study,nitrogen-doped carbon HoMS(NC HoMS)was created using polymer templates through a precisely controlled polymerization process.Batteries featuring NC HoMS-modified separators exhibit improved capacity and cycling stabi-ity in comparison to those utilizing commercial separators.Especially,triple-shelled NC HoMS strikes a balance in polysulfide containment and lithium ion transport.Featuring a sulfur loading of 6.34 mg/cm2,the Li-S battery can consistently complete 100 charge-discharge cycles,starting with a discharge capacity of 966.4 mA·h/g with a 75.8%capacity retention rate.NC HoMS holds potential as the separator modifier in addressing the polysulfide shuttle problem and facilitating the Li-ion transportation for advanced Li-S batteries.

    查看更多>>摘要:Thienoacenes is one of most important groups of semiconducting materials due to the high stability and superior mobility.However,there are scarce studies on the emission properties of thienoacenes to date.Herein,we synthesized fluorinated and chlorinated dibenzo[d,d']thieno[3,2-b;4,5-b']dithiophenes(DBTDTs)derivatives F6-DBTDT and C16-DBTDT by sulfoxide cyclization,significantly lowering the energy levels relative to the parent compound DBTDT.According to single crystal structure analysis,F6-DBTDT molecules adopt one-dimensional slipped stacking with close π-π interactions of 3.43 Å(1 Å=0.1 nm),which is different from the parent compound DBTDT with herringbone stacking motif.Interestingly,the halogenated DBTDT derivatives exhibit enhanced emission properties both in solution and in the solid state,opening up possiblities to improve photoluminescence of thienoacences by halogenation.

    查看更多>>摘要:Hollow zeolite microspheres have recently attracted much attention for their applications in catalysis,microreactors and biomedicine.Herein,we present hierarchically structured zeolite ZSM-5 microspheres with unique,abundant macropores that allow more efficient use for catalysis.The hierarchically macroporous zeolite ZSM-5 microspheres are synthesized under the assistance of water/oil emulsions and using polystyrene nanospheres as templates.The zeolite microsphere is assembled by uniform hollow zeolite nanospheres.Their large inner cavities and thin zeolite shells lead to smaller diffusion channel and higher improved accessibility to active sites,contributing to high catalytic performance in the catalytic conversion of benzyl alcohol in mesitylene.Such novel zeolite microspheres with impressive performance will be applied to numerous other industrial catalytic reactions.

    查看更多>>摘要:Recently,the rapid development of non-fullerene acceptors(NFAs)has laid the foundation for performance improvements in near-infrared(NIR)organic photodetectors(OPDs).However,reducing the bandgap of NFAs to achieve strong absorption in the shorter-wave region usually leads to increased dark current density(Jd)and decreased responsivity(R),severely limiting the detectivity(D*)of NIR-OPDs.To date,it remains challenging to manipulate the Jd of NIR-OPDs through rational structure engineering of NFAs.Herein,three NIR-NFAs,namely bis(2-decyltetradecyl)4,4'-(2',7'-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,9'-fluorene]-2,6-diyl)bis(6-(((Z)-1-(dicyanomethylene)-5,6-difluoro-3-oxo-1,3-dihydro-2H-inden-2-ylidene)methyl)thieno[3,4-b]thiophene-2-carboxylate)(TSIC-4F),bis(2-decyltetradecyl)6,6'-(2',7'-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,9'-fluorene]-2,6-diyl)bis(4-(((Z)-1-(dicyanomethylene)-5,6-difluoro-3-oxo-1,3-d ihydro-2H-inden-2-ylidene)methyl)thieno[3,4-b]thiophene-2-carboxylate)(STIC-4F),and 2,2'-((2Z,2'Z)-(((2',7'-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b']dithiophene-4,9'-fluorene]-2,6-diyl)bis(2,3-bis(5-(2-butyloctyl)thiophen-2-yl)thieno[3,4-b]pyrazine-7,5-diyl))bis(metha-neylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-lH-indene-2,1-diylidene))dimalononitrile(TPIC-4F),were designed using the thieno[3,4-b]thiophene(TT)and thieno[3,4-b]pyrazine(TPy)derivatives as the it-bridge.Owing to the intramolecular S-S and S-N interactions,STIC-4F and TPIC-4F exhibited smaller backbone distortions than下SIC-4F.A significantly red-shifted absorption with a peak at 1015 nm was observed in TPIC-4F film,larger than that(ca.960 nm)for TSIC-4F and STIC-4F films.Moreover,OPDs operating in a photovoltaic mode were successfully fabricated,and TPIC-4F-based OPDs achieved the lowest Jd of 3.18×10-8 A/cm2 at-0.1 V.Impressively,although TPIC-4F-based OPDs exhibited the lowest R,higher shot-noise-limited specific detectivity(Dsh*)in 1000-1200 nm could be achieved due to its lowest Jd.This study underscored the effectiveness of optimizing the 7T-bridge structure of NFAs to suppress Jd,ultimately attaining higher Dsh* in the NIR region.

    查看更多>>摘要:Sodium gluconate(SG)is reported as an electrolyte additive for rechargeable aqueous zinc batteries.The SG addition is proposed to modulate the nucleation overpotential and plating behaviors of Zn by forming a shielding buffer layer because of the adsorption priority and large steric hindrance effect,which contributes to limited rampant Zn2+diffusion and mitigated hydrogen evolution and corrosion.With the introduction of 30 mmol/L SG in 2 mol/L ZnS04 electrolyte,the Zn anode harvests a reversible cycling of 1200 h at 5 mA/cm2 and a high average Coulombic efficiency of Zn plating/stripping(99.6%).Full cells coupling Zn anode with V2O5·1.6H2O or polyaniline cathode far surpass the SG additive-free batteries in terms of cycle stability and rate capability.This work provides an inspiration for design of a high-effective and low-cost electrolyte additive towards Zn-based energy storage devices.

    查看更多>>摘要:Unsaturated ketones are typical oxygenated volatile organic compounds(OVOCs)with high reactivity,and are important precursors in air pollution.The sources of OVOCs are complex and include direct emissions and secondary oxidation formation of VOCs in the atmosphere.2-Cyclohexen-1-one is a widespread substance,and is derived from the industrial catalytic oxidation of cyclohexene.In this paper,we investigated the rate constants of the chemical reactions of 2-cyclohexen-1-one with NO3 radicals,which is(7.25±0.29)×10-15 cm3·molecule-1·s-1 at 298 K and under 1 atm(1 atm=101325Pa).It supplemented the kinetics of NO3 radicals database,and revealed its effects in the nighttime atmosphere.In addition,the reaction products of 2-cyclohexen-1-one with N03 radicals were detected by Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS),which revealed a series of nitrate esters in the composition of the secondary organic aerosol(SOA),which may reduce atmospheric visibility.Finally,the possible pathways for the generation of the products were developed.
