Shi, Yingying;Xu, Qiuchen;Tian, Zhangmin;Liu, Guiying;Ma, Chenxu;Zheng, Wenjun research published 《 Ionic liquid-hydroxide-mediated low-temperature synthesis of high-entropy perovskite oxide nanoparticles》, the research content is summarized as follows. High-entropy perovskite oxides (HEPOs) are attracting significant attention due to their unique structures, unprecedented properties and great application potential in many fields, while available synthetic methods have many shortcomings; so it is still a challenge to develop a simple, low-cost and environment-friendly synthetic strategy for HEPOs. Herein, a novel synthetic strategy is reported for HEPOs using an ionic liquid (IL)-hydroxide-mediated technique at a low temperature and normal atm. pressure. The synthesized HEPOs, including Ba(FeNbTiZrTa)O₃, Ba(MnNbTiZrTa)O₃, Ba(FeSnTiZrTa)O₃ and Ba(FeVTiZrTa)O₃, exhibit a cubic structure and a dispersed nanoparticle morphol. (particle size of 20-60 nm). The formation process of HEPOs in an IL-KOH system can be described as follows: first, B-site metal source compounds are dissolved in IL-KOH medium to form hydroxyl complexes; second, the complexes further dehydrate, condensate and react with Ba²⁺ ions to form the crystal nuclei of HEPOs under the synergistic effect of reaction temperature and basicity; third, the growth of HEPO nuclei is completed by the Ostwald ripening process. In these processes, KOH not only plays a role as a solvent, but also provides sufficient OH- concentration for the formation and condensation of B-site metal hydroxyl complexes, while the IL also makes significant contributions: first, a lower reaction temperature and lower dosage of KOH are achieved by the use of the IL; second, the IL with good dissolving ability and low surface tensions can promote the nucleation rate of HEPOs and improve the Ostwald ripening process; third, the compact adsorption of the IL on the surface of products ensures a small particle size and high dispersion of HEPO nanoparticles to a certain extent. In brief, the technique provides an innovative, low-cost, simple and nontoxic strategy for the synthesis of HEPOs, which can be extended to other high-entropy materials.

The continued success of ionic liquids in applications ranging from energy to medicine poses the challenge to rapidly find new functional ionic liquids with desirable properties while developing practical, scalable syntheses. As a SuFExable functionality, the sulfonyl fluoride has become widely adopted throughout the field of chem. biol. due, in part, to its unique stability-reactivity pattern, highlighting the underappreciated potential of the SVI-F motif in materials chem. For the first time, we herein report the development of a set of sulfonyl fluoride-functionalized ionic liquids with considerable structural diversity via an efficient, modular, and orthogonal fluorosulfonylethylation procedure. The resulting SO₂F-functionalized ionic milieu has properties consistent with its classification as ionic liquids We employed a combination of mol. design, synthesis, computational modeling, and X-ray crystallog. studies to gain in-depth understanding of their structure-property correlations. The diversification of the SO₂F-bearing salts is extended to include active pharmaceutical precursors, allowing for access to functional materials with a priori low toxicity.

So, Yujin;Bae, Hyeon-Su;Kang, Yi Young;Chung, Ji Yun;Park, No Kyun;Kim, Jinsoo;Jung, Hee-Tae;Won, Jong Chan;Ryou, Myung-Hyun;Kim, Yun Ho research published 《 Eco-Friendly Water-Processable Polyimide Binders with High Adhesion to Silicon Anodes for Lithium-Ion Batteries》, the research content is summarized as follows. Silicon is an attractive anode material for lithium-ion batteries (LIBs) because of its natural abundance and excellent theor. energy d. However, Si-based electrodes are difficult to commercialize because of their significant volume changes during lithiation that can result in mech. damage. To overcome this limitation, we synthesized an eco-friendly water-soluble polyimide (W-PI) precursor, poly(amic acid) salt (W-PAmAS), as a binder for Si anodes via a simple one-step process using water as a solvent. Using the W-PAmAS binder, a composite Si electrode was achieved by low-temperature processing at 150 °C. The adhesion between the electrode components was further enhanced by introducing 3,5-diaminobenzoic acid, which contains free carboxylic acid (-COOH) groups in the W-PAmAS backbone. The -COOH of the W-PI binder chem. interacts with the surface of Si nanoparticles (SiNPs) by forming ester bonds, which efficiently bond the SiNPs, even during severe volume changes. The Si anode with W-PI binder showed improved electrochem. performance with a high capacity of 2061 mAh g^-1 and excellent cyclability of 1883 mAh g^-1 after 200 cycles at 1200 mA g^-1. Therefore, W-PI can be used as a highly effective polymeric binder in Si-based high-capacity LIBs.

Schafer, Fabian;Neumann, Beate;Stammler, Hans-Georg;Mitzel, Norbert W. research published 《 Hexadentate Poly-Lewis Acids Based on 1,3,5-Trisilacyclohexane》, the research content is summarized as follows. We report the preparation of hexadentate poly-Lewis acids (PLA) based on 1,3,5-trisilacyclohexane backbones bearing two alkynyl groups attached to each of the silicon atoms. A rigid hexadentate PLA bearing six Lewis-acidic catecholatoboryl-substituents was prepared by a tin-boron exchange reaction. Its structure, determined by X-ray diffraction, is the first of a Lewis-acid-functionalised donor-free trisilacyclohexane. Flexible hexadentate PLA were prepared by hydroboration or hydrosilylation of hexavinyltrisilacyclohexane, resulting in PLA with six 9-BBN, SiCl₃, SiCl₂Me or SiClMe₂ groups. The Lewis-acidity of the last one was increased by conversion with silver triflate, resulting in a PLA with six highly acidic silyl triflate groups attached to the 1,3,5-trisilacyclohexane unit as TfOSiMe₂-C₂H₄– groups. Host-guest experiments of the above PLA demonstrated the suitability of the flexible representatives for complexation of neutral Lewis-based guest mols. under formation of 1 : 6 adducts (host: guest).

Qian, Xinye;Li, Fang;Jin, Lina research published 《 MOF drived MnO/N-C/CNT composite and its modified separator for advanced Li-S battery》, the research content is summarized as follows. The shuttle effect of lithium polysulfides (LPSs) is the main issue which prohibits the practical use of Li-S batteries (LSBs). Therefore, a MnO decorated Nitrogen doped carbon/CNT (MnO/N-C/CNT) composite is synthesized and used as the barrier and accelerator for LPSs. The bi-metal Zn/Mn-MOF is firstly grown on carbon nanotubes (CNT) by a facile chem. reaction of Zn(NO₃)₂/Mn(NO₃) and dimethylimidazole, then the precursor is calcined in nitrogen ambient at 910°C to fabricate MnO/N-C/CNT composite. After coating on the polypropylene separator, the MnO/N-C/CNT layer can greatly alliviate the shuttle effect by its dual function. The N-C/CNT network can provide good conductivity and phys. barrier, while the polar MnO can enhance the chem. adsorption and conversion rate for LPSs. As a result, when the sulfur areal loading is 3.5mg/cm², an impressive specific capacity of 950 mAh/g at 0.5C is obtained by use of MnO/N-C/CNT modified separator, and it can cycle steadily for over 500 cycles at an average decay rate of 0.022%/cycle. Furthermore, the battery also displays a cycle stability for over 200 cycles even under the sulfur areal loading of 5.5mg/cm², which demonstrate its application potential.

The membranes were cast by solution casting method yielding transparent, flexible, and rigid membranes. The phys. properties of the membrane, such as ion exchange capacity (IEC), water absorption, and swelling behavior, were investigated. A comparative study of imidazolium and benzimidazolium functionalized PPO membrane focusing on hydroxide conductivity, and alk. stability was comprehensively examined The C2 substituted Me imidazolium membrane displayed unique morphol. and conductivity of 15 mSCm-1 at 25°C. Due to the sterically protected Me group at the C2 position, imidazolium functionalized PPO membrane showed higher alk. stability for 700 h. Furthermore, benzimidazolium cations would be more easily attacked by a nucleophile (OH-) than imidazolium cations, resulting in ring-opening of the heterocyclic ring.

Ravula, Sudhir;O’Harra, Kathryn E.;Watson, Keith A.;Bara, Jason E. research published 《 Poly(ionic liquid)s with Dicationic Pendants as Gas Separation Membranes》, the research content is summarized as follows. Poly(norbornene)s and poly(ionic liquid)s are two different classes of attractive materials, which are known for their structural tunability and thermal stabilities, and have been extensively studied as gas separation membranes. The incorporation of ionic liquids (ILs) into the poly(norbornene) through post-polymerization has resulted in unique materials with synergistic properties. However, direct polymerization of norbornene-containing IL monomers as gas separation membranes are limited. Subsequently, the poly(NBM-mIm) with bistriflimide [Tf₂N^–] and poly([NBM-DILs][Tf₂N]₂) comprising homo-, random-, and block- (co)polymers were synthesized via ring-opening metathesis polymerization using the air-stable Grubbs second-generation catalyst. Block copolymers (BCPs), specifically, [NBM-mIM][Tf₂N] and [NBM-ImCnmIm] [Tf₂N]₂ (n = 4 and 6) were synthesized at two different compositions, which generated high mol. weight polymers with decent solubility relative to homo- and random (co)polymers of [NBM-DILs] [Tf₂N]₂. The prepared BCPs were efficiently analyzed by a host of anal. tools, including ¹H-NMR, GPC, and WAXD. The successfully BCPs were cast into thin membranes ranging from 47 to 125μm and their gas (CO₂, N₂, CH₄, and H₂) permeations were measured at 20°C using a time-lag apparatus These membranes displayed modest CO₂ permeability in a non-linear fashion with respect to composition and a reverse trend in CO₂/N₂ permselectivity was observed, as a usual trade-off behavior between permeability and permselectivity.

Colloidal photocatalysts can utilize solar light for the conversion of CO₂ to carbon-based fuels, but controlling the product selectivity for CO₂ reduction remains challenging, in particular in aqueous solution Here, we present an organic surface modification strategy to tune the product selectivity of colloidal ZnSe quantum dots (QDs) towards photocatalytic CO₂ reduction even in the absence of transition metal co-catalysts. Besides H₂, imidazolium-modified ZnSe QDs evolve up to 2.4 mmol_CO g_ZnSe^-1 (TON_QD > 370) after 10 h of visible light irradiation (AM 1.5G, λ > 400 nm) in aqueous ascorbate solution with a CO-selectivity of up to 20%. This represents a four-fold increase in CO-formation yield and 13-fold increase in CO-selectivity compared to non-functionalized ZnSe QDs. The binding of the thiolated imidazolium ligand to the QD surface is characterized quant. using ¹H-NMR spectroscopy and isothermal titration calorimetry, revealing that a subset of 12 to 17 ligands interacts strongly with the QDs. Transient absorption spectroscopy reveals an influence of the ligand on the intrinsic charge carrier dynamics through passivating Zn surface sites. D. functional theory calculations indicate that the imidazolium capping ligand plays a key role in stabilizing the surface-bound *CO₂^– intermediate, increasing the yield and selectivity toward CO production Overall, this work unveils a powerful tool of using organic capping ligands to modify the chem. environment on colloids, thus enabling control over the product selectivity within photocatalyzed CO₂ reduction

Peng, Tao;Huang, Jiarong;Gong, Zhou;Ding, Jianping;Chen, Yukun research published 《 Multiple cross-linked networks enhanced ENR-based composite with excellent self-healing properties》, the research content is summarized as follows. Self-healing property is an excellent feature that can improve the reliability and durability of the materials. In this study, carboxylic multi-walled carbon nanotubes (S-CNTs) and 2,2′-dithiodibenzoic acid (DTSA) were introduced into epoxidized natural rubber (ENR) to prepare a self-healing rubber. S-CNTs and DTSA could react with epoxy groups of ENR to effectively cross-link ENR, in which the cross-linked network consisted of reversible disulfide bonds, β-hydroxyl ester bonds, and hydrogen bonds. The reconfigurable cross-linked network endowed the ENR/S-CNTs/DTSA composites with great self-healing behavior with efficiency up to 99.7%. The multiple cross-linked networks also enhanced the mech. properties of the composite, whose tensile strength reached more than 400% of the neat ENR. Addnl., optical microscope and SEM disclosed the evolution of the damaged area during the self-healing process, and the crack could be completely repaired after the healing process. This work provides an effective and concise method to prepare self-healing ENR-based elastomer, and it may expand the research scope of self-healing materials.
