Kaur, Ramanjeet published the artcileA thermodynamic investigation of the effect of cationic structure on the self-aggregation behavior of Surface-Active ionic liquids in the presence of an amino acid, Application of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 118904, database is CAplus.

A series of imidazolium-based ionic liquids (ILs) with varying side alkyl chain length at N3 position which includes [C12mim][Br], [C12eim][Br], and [C12bim][Br] have been synthesized and characterized by ¹H NMR. Then, their aggregation behavior in the presence of different concentrations of the amino acid L-Tryptophan (L-Trp) at different temperatures has been examined using conductometric, tensiometric, and UV-vis (absorption spectra) techniques. The critical micelle concentration (CMC) of ILs has been investigated in the absence and presence of amino acid to acquire a better understanding of the colloidal behavior of ILs in presence of amino acid as an external additive. The addition of amino acid is observed to reduce the CMC values of the ILs examined in an aqueous media. Likewise, applying a charged pseudo-phase model of micellization, the thermodn. parameters of micellization, such as a change in standard free energy (ΔGom), change in standard enthalpy (ΔHom), and change in standard entropy (ΔSom), have been scrutinized from the dependence of CMC on temperature The surface tension approach was also used to evaluate interfacial characteristics. It was discovered that increasing the length of the side chain increases surface activity. All of the estimated parameters were utilized to determine the electrostatic and hydrophobic contributions of IL to the formation of micellar aggregates.

Sharma, Ravinder published the artcileVolumetric and acoustic properties of L-phenyl glycine and L-phenylalanine in aqueous solution of 1-dodecyl-3-methylimidazolium bromide [C₁₂mim] [Br], Recommanded Product: 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 119014, database is CAplus.

To study the mol. interactions between the ternary mixtures containing long chain imidazolium based ionic liquid as a common solvent with substituted amino acids L-Ph glycine and L-phenylalanine resp., densities and speed of sound have been measured at three different temperatures viz. T = 288.15 K, 298.15 K, 318.15 and 318.15 K under 0.1 MPa pressure. The d. and speed of sound data have been further utilized to calculate the apparent molar volume and apparent molar isentropic compression. From the data obtained, apparent molar volume (V_ϕ), partial molar volume (V⁰_ϕ), and standard partial molar volumes of transfer (ΔV⁰_ϕ). Pos. values of apparent molar volume indicate strong interactions. Also, partial molar isentropic compression of transfer (ΔK⁰_ϕ,S) and partial molar isentropic compression (K_ϕ,S) have been calculated from the sound of speed. Furthermore, structure making and structure breaking ability of solute have been discussed by evaluation of apparent molar expansivity, (ϕ⁰_E), Hepler′s constant values (∂/∂T)p. The obtained results have been discussed in terms of solvation behavior, structural changes and various interactions present in different ternary mixtures (1-dodecyl-3-methylimidazolium bromide + amino acids + water).

Liu, Zui published the artcileManipulated and Improved Photoinduced Deformation Property of Photoresponsive Liquid Crystal Elastomers by Copolymerization, Category: bromides-buliding-blocks, the publication is Macromolecular Rapid Communications (2022), 43(6), 2100717, database is CAplus and MEDLINE.

Photoresponsive liquid crystal elastomers (LCEs) have aroused much attention due to their unique structures, properties, and potential applications. However, many reported photoresponsive LCEs show small photoinduced deformation with a slow deformation speed, which limits their application to a certain extent. In this article, multiple hydrogen bond component and biphenyl component was introduced into photoresponsive LCEs bearing cyanostilbene by copolymerization, and prepared a series of LCEs CSm-BPn (CS and BP means cyanostilbene and biphenyl component, resp.; m, n means the content ratio of CS and BP). All uniaxially oriented CSm-BPn fibers show photoinduced deformation behavior under 365 nm UV light except for CS0-BP5. The introduction of hydrogen bond and the decrease of glass transition temperature realize large deformation and fast deformation speed. Besides, the properties of LCEs are successfully regulated by changing the content ratio of each component. What’s more interesting is that the addition of appropriate amount of biphenyl can significantly improve and manipulate the deformation property of the CSm-BPn fibers. The maximum bending angle can reach 175°, and the whole photoinduced deformation process only takes 11 s. The photoresponsive LCEs with such large bending angle and fast deformation rate are rarely reported.

Mishra, Anamika published the artcileSynthesis and properties of 3,4-dioxythiophene and 1,4-dialkoxybenzene based copolymers via direct C-H arylation: Dopant-free hole transport material for perovskite solar cells, Quality Control of 143-15-7, the publication is Journal of Polymer Science (Hoboken, NJ, United States) (2022), 60(6), 975-984, database is CAplus.

Direct C-H arylation coupling reaction has gained significant importance in synthesis of conjugated polymers for organic electronic applications. We report here a facile and straightforward method called “direct C-H arylation” reaction to synthesize conjugated 3,4-dioxythiophene and 1,4-dialkoxybenzene based copolymers as hole transport material (HTM) for perovskite solar cells. Two electron-rich conjugated polymers P1-2 were synthesized, in which 1,4-dibromo-2,5-bis(dodecyloxy)benzene and 3,4-dialkoxy-thiophene units were used for polymerization The resulting polymers were characterized and exhibited high solubility in organic solvents. Electrochem. and optical characterizations were carried out by cyclic voltammetry and UV-Vis-NIR absorption spectroscopy and found that these polymers show higher-lying HOMO energy levels with wide band gap. D. functional theory calculation was performed on these polymers (P 1-2) and correlated with our exptl. results. Finally, perovskite solar cells were fabricated by solution-processable deposition of P1-2 as dopant-free HTM with device geometry ITO/SnO₂/Perovskite/HTM(P1/P2)/Ag and achieved a maximum power conversion efficiency of 5.28%. This study provides information on designing and simple preparation by direct C-H arylation reaction of higher-lying HOMO energy level polymer as HTM for perovskite solar cells.

The synthesis and biol. evaluation of novel guanidino sugars as iso-nucleoside analogs is described. 5-Guanidino xylofuranoses containing 3-O-saturated/unsaturated hydrocarbon or aromatic-containing moieties were accessed from 5-azido xylofuranoses via reduction followed by guanidinylation with N,N’-bis(tert-butoxycarbonyl)-N”-triflylguanidine. Mols. comprising novel types of iso-nucleosidic structures including 5-guanidino 3-O-methyl-branched N-benzyltriazole iso-nucleosides and a guanidinomethyltriazole 3′-O-dodecyl xylofuranos-5′-yl iso-nucleoside were accessed. The guanidinomethyl triazole derivative and a 3-O-dodecyl (N-Boc)guanidino xylofuranose were revealed as selective inhibitors of acetylcholinesterase (K_i=22.87 and 7.49μM, resp.). The latter also showed moderate antiproliferative effects in chronic myeloid leukemia (K562) and breast cancer (MCF-7) cells. An aminomethyltriazole 5′-iso-nucleoside was the most potent mol. with low micromolar GI₅₀ values in both cells (GI₅₀=6.33μM, 8.45μM), similar to that of the drug 5-fluorouracil in MCF-7 cells. Moreover, the most bioactive compounds showed low toxicity in human fibroblasts, further indicating their interest as promising lead mols.

Liu, Shaohui published the artcileEffect of Decarboxylation on the Photoinitiation Behavior of Nitrocarbazole-Based Oxime Esters, Computed Properties of 143-15-7, the publication is Macromolecules (Washington, DC, United States) (2022), 55(7), 2475-2485, database is CAplus.

A series of 50 oxime esters bearing various substituents were designed and synthesized as photoinitiators (48 of them were never synthesized before and only B1 and B10 were reported). Good light absorption properties in the visible range were observed for these oxime esters. Some structures exhibited better photoinitiation abilities than diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) upon exposure to a LED@405 nm. Interestingly, PIs with Me substituent on the oxime ester group have better photoinitiation performance than the others. Substituent effects were investigated through MOs calculations, the detection of CO₂, and the investigation of the generated free radicals. The results demonstrate that the substituents on the oxime ester group exert major effects on the photoinitiation ability via the decarboxylation reaction. In addition, a chem. mechanism was proposed. 3D printed objects were successfully obtained by using the most reactive oxime ester as photoinitiator, and their thermal initiation behaviors of several oxime esters were also studied (dual thermal/photochem. initiator behavior).

Sorci, Mirco published the artcileVirucidal N95 Respirator Face Masks via Ultrathin Surface-Grafted Quaternary Ammonium Polymer Coatings, HPLC of Formula: 143-15-7, the publication is ACS Applied Materials & Interfaces (2022), 14(22), 25135-25146, database is CAplus and MEDLINE.

N95 respirator face masks serve as effective phys. barriers against airborne virus transmission, especially in a hospital setting. However, conventional filtration media materials, such as nonwoven polypropylene fibers, have no inherent virucidal activity, and thus, the risk of surface contamination increases with wear time. The ability of face masks to protect against infection can be likely improved by incorporating components that deactivate viruses on contact. We present a facile method for covalently attaching antiviral quaternary ammonium polymers to the fiber surfaces of nonwoven polypropylene fabrics that are commonly used as active filtration materials in N95 respirators via UV-initiated grafting of biocidal agents. Here, C₁₂-quaternized benzophenone is simultaneously polymerized and grafted onto melt-blown or spunbond polypropylene fabric using 254 nm UV light. This grafting method generated ultrathin polymer coatings which imparted a permanent cationic charge without grossly changing the fiber morphol. or air resistance across the filter. For melt-blown polypropylene, which comprises the filtration layer of N95 respirator masks, filtration efficiency was neg. impacted from 72.5 to 51.3% for uncoated and coated single-ply samples, resp. Similarly, directly applying the antiviral polymer to full N95 masks decreased the filtration efficiency from 90.4 to 79.8%. This effect was due to the exposure of melt-blown polypropylene to organic solvents used in the coating process. However, N95-level filtration efficiency could be achieved by wearing coated spunbond polypropylene over an N95 mask or by fabricating N95 masks with coated spunbond as the exterior layer. Coated materials demonstrated broad-spectrum antimicrobial activity against several lipid-enveloped viruses and Escherichia coli bacteria. For example, a 4.3-log reduction in infectious MHV-A59 virus and a 3.3-log reduction in infectious SuHV-1 virus after contact with coated filters were observed, although the level of viral deactivation varied significantly depending on the virus strain and protocol for assaying infectivity.

El-Saeed, H. M. published the artcileSynthesis and characterization of novel ionic liquids based on imidazolium for acid corrosion inhibition of aluminum: Experimental, spectral, and computational study, Application of 1-Bromododecane, the publication is Journal of Molecular Liquids (2022), 119177, database is CAplus.

Three newly ionic liquids I [R = C₈H₁₇, C₁₀H₂₁, C₁₂H₂₅] were synthesized and their chem. structures characterized via different spectra techniques (FT-IR, elemental anal., and ¹H NMR). The corrosion inhibition of newly ionic liquids was evaluated on aluminum alloy in 1 M HCl at varied exposure temperatures (298-318 K) and varied concentrations via various exptl. and theor. methods for example mass loss, electrochem., spectral, and computational calculations The results illustrate that these types of ionic liquids inhibit corrosion of aluminum in acid solution with maximum inhibition efficiency was reached 83.2% at 298 K. The inhibition efficiency increases with the addition of zinc sulfate which had a synergistic impact which was reached to 92.7%. Also, the concentration of ionic liquids and the kind of cation have an impact on the obtained results. The existence of these inhibitors in the acidic solution improves the charge transfer resistance and lessens the double-layer capacitance. The Langmuir adsorption isotherm governs the adsorption of these inhibitors’ mols. on the aluminum alloy surface, and they behave as mixed-type inhibitors. The outputs reveal that the computational calculations match the exptl. data rather well.
