Prabu, Selvam published the artcileFerrocene appended Y-shaped imidazole aldehyde chromophores: Synthesis, the effect of alkyl chain in the second order nonlinear optical properties and theoretical studies, Recommanded Product: 1-Bromooctane, the publication is Journal of Molecular Structure (2022), 133137, database is CAplus.

Two new Y-shaped ferrocene (Fc) conjugated imidazole (IM) aldehyde [(D-π)2-IM-π-A] type chromophores [(Fc-CH:CH)₂-IM-R-C₆H₄-CHO] {R= H (1); C₈H₁₇ (2)} have been synthesized and characterized with the aid of anal. and spectroscopic techniques [FT-IR, ESI-Mass, ¹H and ¹³C NMR]. The thermal stability of the chromophores 1 and 2 were investigated using thermogravimetric anal. (TGA), and the chromophores were stable up to 160°C. The solvatochromic studies of the chromophores 1 and 2 show a pos. solvatochromism due to the more polarizable and greater stabilization in the excited state than ground state, when solvent polarity was increased from non-polar to polar. The redox behavior of the chromophores were determined by cyclic voltammetry, and the exptl. observed HOMO and LUMO energy levels were good agreement with the DFT. The second harmonic generation efficiencies (SHG) were investigated by the Kurtz-Perry powder technique using potassium dihydrogen phosphate (KDP) as a standard The SHG efficiencies of the chromophore 2 is 2.5 times greater than that of the chromophore 1, because of the presence of n-octyl group which reduces the anti-parallel alignments in mol. packing of the chromophore 2. In addition, the dipole moment (μ) and hyperpolarizability (β₀) were calculated using different functionals (B3LYP, CAM-B3LYP and LC-BLYP), and the B3LYP-hybrid functional is overestimated when compared with long-range CAM-B3LYP and LC-BLYP functionals, because of the uncorrected long-range charge transfer behavior between donor and acceptor in the d-π-A systems. The chromophore 2 shows higher β₀ values in all the different functionals than the 1, due to the presence of the n-octyl group, which restricts the mol. mobility and makes effective charge transfer process of the chromophore 2. The theor. observed results followed the same trend as exptl. results.

Jimoh, Tajudeen A. published the artcileBiological evaluation and docking study of synthesized derivatives of benzotriazole and benzimidazole as antibacterial agents, Product Details of C8H17Br, the publication is Chemistry Africa (2022), 5(3), 509-523, database is CAplus.

To tackle the menace of multi-resistant bacteria which pose challenges to scientist, four benzotriazole derivatives and three benzimidazole derivatives were synthesized via two routes due to the importance of heterocyclic compound in medicinal chem. Two protein target DNA gyrase with PDB ID 2XCT and PDB ID 3ILW were docked with the synthesized compound and compared with the two standard drugs sparfloxacin and ciprofloxacin. For benzotriazole derivatives, the reaction in acetonitrile resulted in lower yields (18-25%) than with dimethylformamide/potassium hydroxide (DMF/KOH), which generated higher yields (68-92%) in shorter reaction time. Those of benzimidazole were comparable. The products were characterized by FTIR, 1H, and 13C NMR, while the association between atoms was shown in 2D NMR. The synthesized compounds were docked against two DNA gyrase with PDB ID 2XCT and PDB ID 3ILW. It was observed that 1-butyl-1H-benzotriazole (- 13.716) and 1-butyl-3-octyl-1H-benzotriazolium (- 12.324) were the most active against PDB ID 2XCT and PDB ID 3ILW, resp. However, they were both less active than the standard drugs used. Using the agar diffusion technique, the synthesized compounds demonstrated broad-spectrum antibacterial activity against gram-pos. and gram-neg. pathogenic bacteria strains. Notably, all the compounds were of varying potency; with inhibition zones ranging from 24 to 30 mm and MIC ranging from 25 to 50 μg/mL. The benzotriazole and benzimidazole derivatives were synthesized successfully. This research revealed that the synthesized compounds were active against organisms with activity, the docking results revealed that the synthesized compounds have relatively low binding energy when compared with the standard drug used as well as those reported earlier. Thus, it will give better interaction on the binding site of the protein. These synthesized compounds could be a source of new drugs that could be used to treat multi-resistance bacteria.

Salman, Abbas Abdulameer published the artcileHybrid emulsifier systems: Alkyl imidazolium lactoside surfactants derived from natural resources, Category: bromides-buliding-blocks, the publication is Carbohydrate Research (2022), 108634, database is CAplus and MEDLINE.

A new series of hybrid surfactants comprising an imidazolium as a cation and a disaccharide as a non-ion were synthesized, and their aggregation behavior was also investigated. The synthetic approach used alkylation as an easily accessible route on an imidazole to attempt an economic production followed by coupling with bromoethyl lactoside to form lacto-imidazolium salts surfactants. The coupled surfactants were obtained in almost quant. yield over several steps. The surfactant surface properties in aqueous media were investigated, including critical micelle concentration (CMC), Krafft temperature, and emulsion stability were studied. The CMC measurements of the alkyl imidazolium lactoside surfactants are significantly lower than normal imidazolium surfactants, while the emulsion investigations encourage the use of alkyl imidazolium lactoside surfactants owing to stabilized assemble behavior as good as APGs.

Liu, Canqun published the artcileStudy on preparation and field induction mechanism of organic silicon composites based on aligned carbon nanotubes, Computed Properties of 111-83-1, the publication is Polymer Engineering & Science (2022), 62(8), 2610-2621, database is CAplus.

High thermal conductivity materials are an urgent need for high power, microelectronic components and equipment, but are limited by low thermal conductivity of the traditional silicone materials. 4-Cyano-4′-n-octyl biphenyl (8OCB) was synthesized to modify carbon nanotubes, and silicone was used as the matrix. In the curing process of the composite, an elec. field was applied and the liquid crystal induced the orientation of carbon nanotubes in the direction of 8OCB liquid crystal. The morphol., structure and properties of modified carbon nanotubes and composites were characterized by Fourier transform IR spectroscopy, polarized microscopy, transmission electron microscopy, thermal conductivity, and so on. The 8OCB liquid crystal can improve the dispersion of carbon nanotubes in silicone composites. When the mass fraction of multiwalled carbon nanotubes (MWCNTs) was 11 wt%, the thermal conductivity of 8OCB-MWCNTs/silicone composite after elec. field was 2.39 W/(m K), which is 6.4 times that of MWCNTs/silicone composite after elec. field and 15.5 times that of pure silicone matrix. A method to obtain highly ordered filled thermal conductive materials by applying an elec. field to induce the orientation of carbon nanotubes is demonstrated.

He, Yang published the artcileImidazolium Gemini ionic liquids for regulating facilely the swelling and dispersion of montmorillonite in water, Category: bromides-buliding-blocks, the publication is Applied Clay Science (2022), 106457, database is CAplus.

The imidazolium Gemini ionic liquids (IL), with alkyl groups ranging from Bu to tetradecyl as tail chains and polyoxyethylene group as linker chain, were synthesized and used as novel efficient modifiers for flexibly controlling the swelling and dispersion of Na-montmorillonite (Na-Mt). The correlation between swelling behavior and structure of imidazolium Gemini IL was investigated. Too long or too short tail chains caused greater swelling, obtaining smaller particle size and reductive face-to-face stacking degree of layers. Based on the change of water contact angles, the increased stability of modified Mt in water indicated that the hydrophobicity of the tail chains played an important role in impeding the entry of water mols. into the interlayer. Zeta potential, Fourier transform IR spectra and XPS validated the cation exchange between imidazolium Gemini IL and Na⁺, and confirmed the adsorption site. The mol. arrangement and intercalation were determined through adsorption behavior, interlayer space of Mt and simulation of mol. size. The imidazolium Gemini IL covered the Mt layers in monolayer, finally taking lateral (short tail chains) or paraffin (long tail chains) arrangement. The investigation will provide useful guidance for modifying Mt to obtain desirable properties and broadening the practical application of Mt hybrids.

Yuan, Xiyue published the artcileAchieving 16% Efficiency for Polythiophene Organic Solar Cells with a Cyano-Substituted Polythiophene, Computed Properties of 111-83-1, the publication is Advanced Functional Materials (2022), 32(24), 2201142, database is CAplus.

Polythiophenes (PTs) are promising electron donors in organic solar cells (OSCs) due to their simple structures and excellent synthetic scalability. However, the device performance of PT-based OSCs is rather poor due mainly to large photon energy losses and an unfavorable active layer morphol. Herein, the authors report a new PT, which is abbreviated as P5TCN-2F and features cyano-group substituents for high-efficiency OSCs. The cyano-group endows P5TCN-2F with a deep-lying HOMO energy level, which thereby contributed to high open-circuit voltage in OSCs as a result of reduced non-radiative recombination energy loss. Moreover, the cyano-group leads to strong interchain interaction, improved polymer crystallinity, and appropriate miscibility with the prevailing non-fullerene acceptors. Consequently, P5TCN-2F offers over 15% power conversion efficiency when blended with various Y-series non-fullerene acceptors (Y6, Y6-BO, eC9, and L8-BO). Particularly, a champion efficiency of 16.1% is obtained by the P5TCN-2F:Y6 blend, which is largely higher than that of any previous PT-based OSCs. Moreover, the average figure of merit of the active layer based on P5TCN-2F is much superior to that of benzodithiophene-based polymers. These results suggest the renaissance of PT-based OSCs and have opened an avenue to access high-performance materials for the large-scale production of OSC modules.

2-Mercapto-5-methyl-1,3,4-thiadiazole (MMT) based ionic liquids were synthesized, their corrosion inhibition behavior and tribol. performance were systematically evaluated. Electrochem. experiments showed MMT based ILs exhibited surprising corrosion inhibition efficiencies. The ILs adsorption behavior obeys Langmuir isotherm. Friction tests demonstrated MMT based ILs performed excellent lubrication properties, compared to [BMIM][BF4]. Combining with anal. of SEM and XPS, it can be concluded that the prominent lubrication performance ascribed to the coexistence of adsorption layer and tribo-film. Therefore, versatile ILs designed in this paper have gathered two significant abilities for industrial applications, which are high corrosion inhibiting performance and excellent lubricating properties. This work is instructive for structure design of multifunctional ILs and will promote industrial application of MMT based ILs in the future.

Public anxiety and concern from cesium pollution in oceans have been back on the agenda since tons of nuclear waste water were announced to be poured into oceans. Cesium ion can easily enter organisms and bioaccumulate in animals and plants, thus its harm is chronic to humans through food chains. Here we showed a kind of hybrid ionic liquid membrane (HILM) for detection of cesium ion in seawater through CsPbBr₃ perovskite fluorescence. With sustainability in mind, HILM was built frugally. The lowest cost of HILM is below 3 cents per piece. The HILM can detect cesium ion quickly with eye-readable fluorescence signal. Ultracheap, portable, easy-to-use on-site detection device could offer benefit for personal security and applications in environment science and ecol. in the future decades.

One-step synthesis and micropatterning of different types of carbon nanomaterials, such as amorphous carbon or three-dimensional graphene which have versatile electrochem., thermal, and mech. properties, are advantageous for the fabrication of microelectronics, sensors, and wearable devices. Here, we report a direct laser writing method to simultaneously synthesize and pattern graphitic carbon from liquid organic precursors. We have tested a wide range of liquid organic precursors and identified the chem. characteristics that are beneficial for successful laser-induced solvothermal deposition. The laser-deposited carbon exhibits a paracryst.-to-polycrystalline structure and has elec. resistivities on the order of 10^-3 to 10^-4 Ω m which is tunable through variations in the laser power. Such properties of the laser-deposited carbon, coupled with the ability to direct-write custom patterns with microscale resolution, make these carbon materials exciting candidates for use in applications such as energy storage and sensing.
