Here we present a rheol. study of enzymic hydrolysis lignin (EH lignin) in 1-butyl-3-methylimidazolium chloride ([C₄min]Cl) aqueous solutions The effects of ionic liquid mass fraction, shear rate and temperature on the viscosity and macromol. chain configuration of EH lignin / [C₄min] Cl aqueous solution were studied. The results showed that the viscosity of the aqueous solutions increased with the increase of lignin content. The mass percentages of overlapping and winding, responding to divisions of lignin macromols. existence state, were varied with changing in the temperature and mass percentages of ionic liquid Increasing the mass of ionic liquid will significantly change the viscosity of lignin solution Most of the lignin solutions had shear thinning behavior, suggesting that macromol. chains of lignin moved with orientation to the fluid, and disentangled under the shear force. The viscosity of lignin solution decreased with the increase of temperature, and the viscosity activation energy increased with the increase of lignin or ionic liquid mass fraction.

Conventional synthesis of carbon dots (CDs) mostly involves a hydrothermal or solvent-thermal reaction which needs relatively high temperature and pressure. In this work, ionic liquid is used to assist in fast synthesizing CDs with an ultrahigh photoluminescent quantum yield (98.5%) by heating at a low temperature (≤100°C) and at atm. pressure. In addition, through this approach, tunable multicolor emissive CDs can be successfully achieved and used for preparing high-performance white light-emitting diodes. Theor. computation proves that the activity of synthesis reaction can be significantly enhanced by ionic liquids D. functional theory calculation reveals that the size and graphite nitrogen ratios of CDs have an effect on bandgap reduction, resulting in a red shift of the emission, which is in good agreement with the exptl. results. This simple and promising approach for fast synthesis of tunable emissive CDs using ionic liquid affords the facilitation of CDs-based luminescent materials for fast manufacturing of functional devices.

In this work, we report large-scale preparation of stable Sb³⁺ and Bi³⁺ codoped Cs₂ZrCl₆ microcrystals for highly efficient white light emission using ionic liquids, demonstrating a broad dual-band white emission covering 400-800 nm. The dual emissions originate from the associated self-trapped excitons of the [SbCl₆]^3- and [BiCl₆]^3- octahedra. Moreover, the ratio of the dual-emission peaks can be effectively regulated by tuning the excitation wavelength. Meanwh000.0.0.0.0.ile, to improve the optical properties and stability, ionic liquids are employed to assist the synthesis process of perovskite materials.

Herein, a striking anion-tunnel transfer effect was demonstrated in 1-butyl-3-methylimidazolium benzoate (BmimPhCOO) ionic liquid, so a rapid, mild and efficient benzoylation of cellulose is accomplished under catalyst-free condition in BmimPhCOO. In a wide temperature range of 20-80°C, the equilibrium of reaction is reached within only 15 min, which is much faster than the reported acylation of cellulose. Furthermore, the resultant cellulose tribenzoates have excellent solubility in conventional organic solvents, thus they can be used to accurately reflect the mol. weight and dispersity index of cellulose raw materials by gel permeation chromatog. This method is suitable for various cellulose. Therefore, we found a new principle to realize the extremely-rapid acylation of cellulose, and proposed an effective approach to accurately determine the mol. weight parameters of cellulose.

Zhang, Xiaofang published the artcileGuiding cellular channels of artificial nanohybrid woods for anisotropic properties and solar-thermal evaporation, Related Products of imidazoles-derivatives, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2022), 132060, database is CAplus.

Natural evolution offers woods with intriguing multicomponent and anisotropic cellular structures, and endows super physicochem. properties. In order to compete with natural woods, many types of artificial woods were endeavored from polymers to achieve on-demand structures and functionalities. In most cases, production of oriented channels in mimic of wood lumina relied on a delicate unidirectional freeze-drying approach and utilization of volatile solvents. Herein we showed that artificial woods with controllable channel orientation could be produced from polymers in involatile solvents without particular control of freezing parameters. By dissolving cellulose in ionic liquid, oriented channels (diameter of 250-540μm) were produced through diffusion-induced phase separation and strengthened through a facile freezing and air-drying process. The compressive strength could reach 5.5 MPa at the strain of 15% along the channel direction. With the presence of structural anisotropy, incorporation of low-dimension nanomaterials offered the design flexibility in adding super properties in mechanics, water transportation, solar-thermal effect, thermal and photo conductance. For example, artificial hybrid woods with carbon nanotubes showed super solar-thermal property. When combining with the water-transporting ability of oriented channels, it was promising to design an efficient solar-thermal evaporator (5.88 kg m^-2 h^-1 under equivalent 3-sun irradiation). Thus, this study not only suggests an unprecedented approach of producing artificial woods from polymers in involatile solvents, but also offers the flexibility of designing microstructures and functionalities of artificial woods for various applications.

Tan, Shuai published the artcileTuning the Charge and Hydrophobicity of Graphene Oxide Membranes by Functionalization with Ionic Liquids at Epoxide Sites, Quality Control of 79917-90-1, the publication is ACS Applied Materials & Interfaces (2022), 14(16), 19031-19042, database is CAplus and MEDLINE.

Functionalization of graphene oxide (GO) membranes is generally achieved using carboxyl groups as binding sites for ligands. Herein, by taking advantage of the ability of imidazolium-based ionic liquids (ILs) to undergo an epoxide ring-opening reaction, a new approach of GO modification was established, in which ILs were bonded to the abundant epoxides on GO without sacrificing the carboxyl groups. Computational methods confirmed this unique configuration of ILs on GO, which enabled the dispersion of IL/GO flakes in water for facile casting into laminate membranes. Compared with neat GO, the ILs in IL/GO membranes served as spacers that substantially reduced the multi-valent cation mobility, simultaneously facilitated ion desolvation, and increased the water flux across the membrane. Our studies found that the higher separation efficiency of IL/GO membranes may be attributed to the synergistic modification of the hydrophobicity and surface charge. Specifically, the protonated nitrogen of the imidazolium cations altered the surface charge of GO, thereby generating electrostatic repulsion that enhanced the selectivity of cation rejection. On the other hand, the increased length of the alkyl chains bound to the imidazolium rings was found to increase the hydrophobicity of GO, which, in turn, aided the fine-tuning of the water desolvation/transport dynamics at the GO/IL interface to achieve a high water flux. Addnl., the water retention was reduced on the hydrophobic planes, which inhibited GO swelling during aqueous separations Mol. dynamics simulations revealed increased water diffusivity when ILs were intercalated within GO layers. We establish that without requiring a high energy input, functionalization of GO membranes with ILs may be a promising approach to achieve efficient ion separation and critical material recovery.

Shekaari, Hemayat published the artcileEffective ultrasonic-assisted extraction and solubilization of curcuminoids from turmeric by using natural deep eutectic solvents and imidazolium-based ionic liquids, Product Details of C8H15ClN2, the publication is Journal of Molecular Liquids (2022), 119351, database is CAplus.

Curcuminoids (CURs), bioactive and antioxidant polyphenols, are major components of turmeric. Com. available component in CURs are curcumin (C) as the main constituent and the other two demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC) as minor components. Extraction and anal. of these components from turmeric may pose specific challenges and yield different results. The organic solvents applied in traditional solvent extraction systems are not eco-friendly owing to their properties such as flammability, toxicity and volatility. For this reason, in this research work, ten deep eutectic solvents (DESs) and three ionic liquids (ILs) were selected to investigate the extraction of CURs from turmeric. Further, DES and ILs-based extraction was performed under ultrasound. Under extraction conditions, the CURs in the turmeric powder was measured by the use of high performance liquid chromatog. (HPLC). The maximum CURs amount of 164.51 mg/g was attained using effective ultrasound-assisted extraction in 50% water content DES or IL at 5% solid loading with 50.8 W/cm2 power intensity at 363 K in 60 min. This improved extraction method can be economical, green and effective alternative to conventional solvent extraction for CURs. On the other hand, the solubility of standard CUR was obtained at 298.15 K using saturation shake flask method. Finally, Hansen solubility parameters (HSP) were applied to identify solvents which were compatible with CURs. All the results were consistent with each other, supporting the validity of our extraction method.

Cho, Chul-Woong published the artcileIn silico prediction and analysis of dielectric constant of ionic liquids, Quality Control of 79917-90-1, the publication is Korean Journal of Chemical Engineering (2022), 39(6), 1651-1657, database is CAplus.

Ionic liquids (ILs) are a class of chems. comprising cations and anions whose properties can be controlled by modifying their chem. structure, which enables a wide range of applications. Among the attractive properties of ILs, dielec. permittivity provides important information related to material solvation and capacitor characteristics. Because there are several ILs and a need to understand the structural effect on their properties, prediction model(s) should be developed. For this, we employed the linear free-energy relationship (LFER) equation to predict the dielec. constant of ILs. In the modeling, we used in silico calculated mol. descriptors because the empirically LFER estimated descriptors were limited. The results revealed that the developed model could predict the dielec. constant with an R² of 0.882. From the developed model, it was observed that the dielec. constant was more affected by the structure of cations compared to that of anions. In addition, the H-bonding acidity of the cation and basicity of the anion contributed to the dielec. property of ILs, and the dipolarity/polarizability of cations and anions was also important in the prediction. The predictive model is expected to be useful for designing IL structures considering the dielec. constant
