Ionic liquids (ILs) have been widely considered and used as “green solvents” for more than two decades. However, their ecotoxicity results have contradicted this view, as ILs, particularly hydrophobic ones, are reported to exhibit high toxicity. Yet the origin of their toxicol. remains unclear. In this work, we have investigated the interaction of amphiphilic ILs with a lipid bilayer as a model cell membrane to understand their cytotoxicity at a mol. level. By employing fluorescence imaging and light and X-ray scattering techniques, we have found that amphiphilic ILs could disrupt the lipid bilayer by IL insertion, end-capping the hydrophobic edge of the lipid bilayer, and eventually disintegrating the lipid bilayer at high IL concentration The insertion of ILs to cause the swelling of the lipid bilayer shows strong dependence on the hydrophobicity of IL cationic alky chain and anions and is strongly correlated with the reported IL cytotoxicity. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Related Products of 404001-48-5).

Catalytic Behavior of Au Confined in Ionic Liquid Film: A Kinetics Study for the Hydrochlorination of Acetylene was written by Wang, Bolin;Zhang, Haifeng;Yue, Yuxue;Li, Changlin;Zhao, Jia. And the article was included in Catalysts in 2022.Recommanded Product: 79917-89-8 This article mentions the following:

A systematic study of the kinetics of supported-ionic-liquid-phase (SILP) Au catalysis (Au-IL/AC) has been established in the continuous gas-phase hydrochlorination of acetylene. We reveal that the effect of ionic liquid (IL) film on substrate diffusion can be eliminated. The reaction order of the catalyst indicates that Au is confirmed to exist as a monomer in the IL film of the Au-IL/AC system, which is different from the fast equilibrium of the “Au dimer and monomer” for the classical Au/AC catalyst. The homogeneous reaction micro-environment is confirmed for Au-IL/AC since the activation energy was little changed under both heterogeneous and homogeneous catalysis, further verifying the monat. characteristics of Au in Au-IL/AC. Due to the supported IL film, the reaction order of hydrogen chloride was decreased from 1 to 0.5 while creating a hydrogen chloride enrichment system around Au, which provides the possibility of producing vinyl chloride with an equal substrates feed ratio. This kinetic-perspective-based revelation of the catalytic behavior of the metal active sites confined in IL film enriches and expands the SILP catalytic system for acetylene hydrochlorination.

Responsive Ionogel Surface with Renewable Antibiofouling Properties was written by Ye, Lijun;Chen, Fei;Liu, Jie;Gao, Aiting;Kircher, Gunnar;Liu, Wendong;Kappl, Michael;Wegner, Seraphine;Butt, Hans-Juergen;Steffen, Werner. And the article was included in Macromolecular Rapid Communications in 2019.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The synthesis of ionogels with a responsive, self-replenishing surface for combating biofouling is described. Ionogels are prepared by infiltrating poly(vinylidene fluoride-co-hexafluoropropylene) with binary mixtures of ionic liquids (IL): 1-octadecyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₁₈C₁i.m.][NTf₂], m.p. T_m = 55 °C) and 1-hexyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([C₆C₁i.m.][NTf₂], T_m = -9 °C). The IL mixtures release spontaneously from the gel matrix and eventually crystallize on the surface. This leads to self-replenishment of the surface of ionogels even after mech. damage. The incorporation of [C₆C₁i.m.][NTf₂] provides the antimicrobial efficacy of ionogels while the crystals of [C₁₈C₁i.m.][NTf₂] serve as a skeleton maintaining [C₆C₁i.m.][NTf₂] on the surface. By heating, the ionogel surface transforms from solid to liquid-infused state-the removal of biofilms/bacteria developed under a long time of colonization is facilitated. The antimicrobial efficacy is maintained even after several cycles of biofilm formation and detachment. This work provides an opportunity to apply ionogels as functional coatings with renewable antibiofouling properties.

New ionic organic compounds containing a linear tris(imidazolium) core and their thermotropic liquid crystal behavior was written by Schenkel, Magdalene R.;Shao, Renfan;Robertson, Lily A.;Wiesenauer, Brian R.;Clark, Noel A.;Gin, Douglas L.. And the article was included in Liquid Crystals in 2013.Computed Properties of C11H20N2 This article mentions the following:

Imidazolium-containing thermotropic ionic liquid crystals (TILCs) are of interest because of their structural similarity to imidazolium-based ionic liquids (ILs), allowing them to exhibit some IL-like properties in addition to the LC order. More imidazolium units are important for increasing the IL character; however, the effect of multiple imidazolium units on LC behavior is not well known. Most reported imidazolium TILCs contain one imidazolium unit; only a handful containing multiple imidazolium units is known. The only examples of TILCs with multiple imidazolium units sequentially linked with a flexible spacer are based on an alkyl- or oligo(ethylene oxide)-bridged bis(imidazolium) core with an n-alkyl tail at each end. Herein, a series of ten new sym. compounds containing three hexyl-bridged imidazolium bromide units as the core and two terminal alkyl chains was synthesized and analyzed. Thermotropic LC phases were generally not observed for homologs with even-numbered tails less than 16 carbons. However, after initial annealing, the homologs containing 16-carbon, 18-carbon and 20-carbon tails, all form a smectic A phase in the 25-137° range, with the latter two also forming a higher-order smectic phase. This indicates that with sufficiently long alkyl tails to counterbalance the poly(ion) core, these tris(imidazolium) salts can exhibit thermotropic mesomorphism. The title compounds thus formed included a tris[imidazolium] tribromide compound (I) [1,3-bis[6-(1-alkyl-1H-imidazolium-3-yl)hexyl]imidazolium tribromide] and related substances. The synthesis of the target compounds was achieved by a reaction of 1,3-bis(6-bromohexyl)-1H-imidazolium bromide with alkyl bromides. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Computed Properties of C11H20N2).

1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Computed Properties of C11H20N2

Ligand-Promoted Rh^I-Catalyzed C2-Selective C-H Alkenylation and Polyenylation of Imidazoles with Alkenyl Carboxylic Acids was written by Zhao, Haoqiang;Luo, Zhenli;Yang, Ji;Li, Bohan;Han, Jiahong;Xu, Lijin;Lai, Wenzhen;Walsh, Patrick J.. And the article was included in Chemistry – A European Journal in 2022.Product Details of 83741-35-9 This article mentions the following:

The first RhI-catalyzed, directed decarbonylative C2-H alkenylation of imidazoles with readily available alkenyl carboxylic acids is reported. The reaction proceeds in a highly regio- and stereoselective manner, providing efficient access to C2-alkenylated imidazoles that are generally inaccessible by known C-H alkenylation methods. This transformation accommodates a wide range of alkenyl carboxylic acids, including challenging conjugated polyene carboxylic acids, and diversely decorated imidazoles with high functional group compatibility. The presence of a removable pyrimidine directing group and the use of a bidentate phosphine ligand are pivotal to the success of the catalytic reaction. This process is also suitable for benzimidazoles. Importantly, the scalability and diversification of the products highlight the potential of this protocol in practical applications. Detailed exptl. and computational studies provide important insights into the underlying reaction mechanism.

A New Model for Prediction of One Electron Reduction Potential of Nitroaryl Compounds was written by Fareghi-Alamdari, Reza;Zandi, Farzad;Keshavarz, Mohammad Hossein. And the article was included in Zeitschrift fuer Anorganische und Allgemeine Chemie in 2015.COA of Formula: C5H5N3O4 This article mentions the following:

This paper introduces a simple model for prediction of one electron reduction potential [E(RNO₂/R^•NO₂^–)] of various nitroaryl compounds The new method uses energy difference between HOMO (HOMO) and LUMO (LUMO) in gas phase at the B3LYP/6-311++G** level (ΔE_HOMO-LUMO) and some structural parameters. It was used for 35 nitroaryl compounds including nitrobenzenes, nitrofurans, 2-nitroimidazoles, 4-nitroimidazoles, 5-ninuintidazoles, nitroazaindoles, nitroacridines, and miscellaneous nitroaryl compounds The root mean square (rms) percent deviation and the average absolute error of predictions of E(RNO₂/R^•NO₂^–) relative to experiment were decreased from 12.4 % and 0.42 V to 3.5 % and 0.11 V, resp., upon consideration of several structural parameters. Increment of the value of ΔE_HOMO-LUMO and inclusion of specific polar groups can increase thermodn. stability of these compounds In the experiment, the researchers used many compounds, for example, 2-(2-Nitro-1H-imidazol-1-yl)acetic acid (cas: 22813-32-7COA of Formula: C5H5N3O4).

Self-Induced Nucleation During the Antisolvent Crystallization Process of Candesartan Cilexetil was written by Gao, Zhenguo;Wu, Yang;Wu, Yuanyi;Gong, Junbo;Bao, Ying;Wang, Jingkang;Rohani, Sohrab. And the article was included in Crystal Growth & Design in 2018.Application In Synthesis of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate This article mentions the following:

We report that the induction time goes through a maximum with increasing the agitation rate, while the majority of studies in the literature have noted a monotonic decrease in the nucleation rate with increasing the agitation rate. Candesartan cilexetil was studied as the model compound during an antisolvent crystallization process. A self-induced nucleation mechanism was proposed based on process tracking anal. by using the focused beam reflectance measurement, in situ Raman spectroscopy, and an off-line differential scanning calorimetry (DSC) instrument. The prenucleation clusters generated by the instantaneous change of local supersaturation during the addition of antisolvent were separated and characterized by powder X-ray diffraction and hot-stage microscopy. Results indicate the prenucleation clusters are an amorphous phase with a lower m.p. compared with the crystalline state. The prenucleation clusters acted as a nucleation inducer at low agitation level to promote the nucleation. On the contrary, the prenucleation clusters dissolved entirely at the high stirring rate before crystal nucleation occurred, which resulted in a maximum in the induction time with the change of stirring speed. In-situ Raman and DSC results combined with the single crystal structure information on acetone solvate show the evolution from prenucleation clusters to solvate crystals. This study helps to understand the nucleation mechanism during the antisolvent crystallization process, especially for the process scale-up with the observed inconsistencies in the nucleation rate with mixing rate. In the experiment, the researchers used many compounds, for example, 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate (cas: 145040-37-5Application In Synthesis of 1-(((Cyclohexyloxy)carbonyl)oxy)ethyl 1-((2′-(2H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-2-ethoxy-1H-benzo[d]imidazole-7-carboxylate).

Making Sense of Enthalpy of Vaporization Trends for Ionic Liquids: New Experimental and Simulation Data Show a Simple Linear Relationship and Help Reconcile Previous Data was written by Verevkin, Sergey P.;Zaitsau, Dzmitry H.;Emelyanenko, Vladimir N.;Yermalayeu, Andrei V.;Schick, Christoph;Liu, Hongjun;Maginn, Edward J.;Bulut, Safak;Krossing, Ingo;Kalb, Roland. And the article was included in Journal of Physical Chemistry B in 2013.Category: imidazoles-derivatives This article mentions the following:

Vaporization enthalpy of an ionic liquid (IL) is a key phys. property for applications of ILs as thermofluids and also is useful in developing liquid state theories and validating intermol. potential functions used in mol. modeling of these liquids Compilation of the data for a homologous series of 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide ([C_nmim][NTf₂]) ILs has revealed an embarrassing disarray of literature results. New exptl. data, based on the concurring results from quartz crystal microbalance, thermogravimetric analyses, and mol. dynamics simulation have revealed a clear linear dependence of IL vaporization enthalpies on the chain length of the alkyl group on the cation. Ambiguity of the procedure for extrapolation of vaporization enthalpies to the reference temperature 298 K was found to be a major source of the discrepancies among previous data sets. Two simple methods for temperature adjustment of vaporization enthalpies have been suggested. Resulting vaporization enthalpies obey group additivity, although the values of the additivity parameters for ILs are different from those for mol. compounds In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Category: imidazoles-derivatives).

The usefulness of ion-pair reagents in selective solid reversed-phase extraction of one N-butyl-4-methylpyridinium and 4 short-chain alkylimidazolium ionic liquid cations from aqueous media was studied using various concentrations of alkylsulfonates with different alkyl chain lengths. Final recoveries of the 2 cations with the shortest alkyl residues were poorer than those of the other, more hydrophobic compounds The recovery values were little affected by the different concentrations of the reagents. In nearly all cases, the best recoveries were obtained with the 1-heptanesulfonate reagent. The anal. performance parameters included excellent linearity over 4 orders of magnitude, with limits of detection 0.01-0.06 ppm, and very good precision and accuracy. The method was used to extract ionic liquids from spiked seawater and freshwater samples. Recoveries and limits of detection were quite similar to those obtained with preconcd. standard solutions In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8HPLC of Formula: 79917-89-8).
