Room temperature ionic liquids (RTILs) represent a promising class of chem. tunable, low vapor pressure solvents with myriad kinetic applications that depend sensitively on the nature of gas-mol. interactions at the liquid surface. This paper reports on rovibronically inelastic dynamics at the gas-RTIL interface, colliding supersonically cooled hyperthermal mol. beams of NO (²Π_1/2, N = 0) from 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (or [C_nmim][Tf₂N]) and probing the scattered NO mols. via laser induced fluorescence (LIF) from the A(²Σ) state. Specifically, inelastic energy transfer into NO rovibrational and electronic degrees of freedom is explored as a function of RTIL alkyl chain length (n), incident collision energy (E_inc) and surface temperature (T_s). At low collision energies (E_inc = 2.7(9) kcal/mol), the scattered NO mols. exhibit a rotational temperature (T_rot) systematically colder than T_s for all chain lengths, which signals the presence of non-equilibrium dynamics in the desorption channel. At high collision energies (E_inc = 20(2) kcal/mol), microscopic branching into trapping/desorption (TD) and impulsive scattering (IS) pathways is clearly evident, with the TD fraction (α) exhibiting a step-like increase between short (n = 2, 4) and long (n = 8, 12, 16) alkyl chains consistent with theor. predictions. For all hydrocarbon chain lengths and RTIL temperature conditions, NO rotational excitation in the IS channel yields hyperthermal albeit Boltzmann-like distributions well described by a “temperature” (T_IS = 900 -1200 K) that decreases systematically with increasing n. Non-adiabatic, collision induced hopping between ground and excited spin-orbit states is found to be independent of RTIL alkyl chain length and yet increase with collision energy. The scattering data confirm previous exptl. reports of an enhanced presence of the alkyl tail at the gas-RTIL interface with increasing n, as well as provide support for theor. predictions of an alkyl length dependent shift between chains oriented parallel vs. perpendicular to the surface normal.

Imidazolium Ionic Liquids as Potential Anti-Candida Inhibitors: QSAR Modeling and Experimental Studies was written by Hodyna, Diana;Kovalishyn, Vasyl;Rogalsky, Sergiy;Blagodatnyi, Volodymyr;Metelytsia, Larisa. And the article was included in Current Drug Discovery Technologies in 2016.Recommanded Product: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

Quant. structure-activity relationships (QSAR) of imidazolium ionic liquids (ILs) as inhibitors of C. albicans collection strains (IOA-109, KCTC 1940, ATCC 10231) have been studied. Predictive QSAR models were built using different descriptor sets for a set of 88 ionic liquids with known min. inhibitory concentrations (MIC) against C. albicans. We applied the state-of-the-art QSAR methodologies such as WEKA Random Forest (RF) as a binary classifier, Associative Neural Networks (ASNN) and k-Nearest Neighbors (k-NN) to build continuum non-linear regression models. The obtained models were validated using a 5-fold cross-validation approach and resulted in the prediction accuracies of 80% ± 5.0 for the classification models and q2 = 0.73-0.87 for the non-linear regression models. Biol. testing of newly synthesized 1,3-dialkylimidazolium ionic liquids with predicted activity was performed by disco-diffusion method against C. albicans ATCC 10231 M885 strain and clin. isolates C. albicans, C. krusei and C. glabrata strains. The high percentage of coincidence between the QSAR predictions and the exptl. results confirmed the high predictive power of the developed QSAR models within the applicability domain of new imidazolium ionic liquids In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Recommanded Product: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

The structures of [MoBr(η³-C₃H₅)(CO)₂(Cl-phen)] and [Mo(CF₃SO₃)(η³-C₃H₅)(CO)₂(dppz)] are determined by using single-crystal X-ray diffraction. These and three complexes of 2,2′-bipyridyl (bpy), and its two derivatives with Me and ^tBu substituents, are tested in the homogeneous catalytic epoxidation of several olefins in dichloromethane, exhibiting, in general, a good selectivity towards the resp. epoxide and relatively low TOFs. For the first time, the oxidation of cis-cyclooctene with some of these catalysts is also conducted in a variety of room-temperature ionic liquids (RTILs). In the presence of [MoBr(η³-C₃H₅)(CO)₂(phen)], the conversions, in general, increase, compared with the reactions in organic solvents. Interestingly, different chemoselectivity is found when [C₆mim][Ntf₂] and [C₂mim][FAP] are used with diol (24-26 %). On the other hand, [MoBr(η³-C₃H₅)(CO)₂(L)] (L = Me-phen or dppz) exhibits much lower conversions in the RTILs tested than in common organic solvents.

Photoexcitation dynamics of p-nitroaniline and N,N-dimethyl-p-nitroaniline in 1-alkyl-3-methylimidazolium-cation based ionic liquids with different alkyl-chain lengths was written by Kimura, Y.;Ibaraki, S.;Hirano, R.;Sugita, Y.;Yasaka, Y.;Ueno, M.. And the article was included in Physical Chemistry Chemical Physics in 2017.Formula: C18H31F6N3O4S2 This article mentions the following:

Photoexcitation dynamics of p-nitroaniline (pNA) and N,N-dimethyl-p-nitroaniline (DMpNA) in 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C_nmim][NTf₂]) with different alkyl chain lengths (from C₂ to C₁₂) was investigated using transient absorption spectroscopy. The internal conversion rate from the excited state to the ground state was estimated from bleach recovery around the ground state absorption center, and the successive vibrational cooling rate in the ground state was estimated from the decay of the hot band observed at the red-edge of ground state absorption. The internal conversion rate slightly decreased with an increase in the alkyl-chain length of the cation, while the dependence of DMpNA was more significant than that of pNA. The extent of change was correlated with the change of the reaction free energy and solvent reorganization energy estimated from the absorption spectrum assuming that the internal conversion process is modeled by a back-electron-transfer process. The vibrational cooling rate estimated from the decay of hot-band absorption slightly decreased with an increase in the alkyl-chain length of the cation for both solutes. The hot-band decay of pNA was about 1.5-times faster than that of DMpNA, irresp. of the alkyl-chain length. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Formula: C18H31F6N3O4S2).

Anions as Dynamic Probes for Ionic Liquid Mixtures was written by Di Pietro, Maria Enrica;Castiglione, Franca;Mele, Andrea. And the article was included in Journal of Physical Chemistry B in 2020.Reference of 404001-48-5 This article mentions the following:

Ionic liquid (IL) mixtures were proposed as a viable alternative to rationally fine-tune the physicochem. properties of ILs for a variety of applications. The understanding of the effects of mixing ILs on the properties of the mixtures is however only in the early stages. Two series of ionic liquid mixtures, based on the 1-ethyl-3-methylimidazolium and 1-dodecyl-3-methylimidazolium cations, and having a common anion (tetrafluoroborate or bis(trifluoromethylsulfonyl)imide), were prepared and deeply characterized via multiple NMR techniques. Diffusion and relaxation methods combined with 2D ion-ion correlation (nuclear Overhauser enhancement) experiments were used for a better understanding of the interplay between dynamics and structure of IL mixtures A crucial role of the anion in driving the mixture’s behavior emerged, making them important “dynamic probes” for gaining information of the polar and nonpolar regions of ionic liquids and their mixtures In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Reference of 404001-48-5).

Solution extraction of several lanthanides from nitric acid with isohexyl-BTP in [C_nmim][NTf₂] ionic liquid was written by Zhao, Long;Dong, Zhen;Ma, Guolong;Yuan, Weijin. And the article was included in Journal of Rare Earths in 2015.Product Details of 404001-48-5 This article mentions the following:

The extraction behavior of several lanthanides (La³⁺, Eu³⁺, Lu³⁺) from nitric acid (HNO₃) solution was studied using a novel extraction system based on 2,6-bis(5,6-dihexyl-1,2,4-triazin-3-yl) pyridine (isohexyl-BTP) as extractant in 1-alkyl-3-methylimidazolium bis(trifluoromethylsufonyl)imide ([C_nmim][NTf₂]) ionic liquid Isohexyl-BTP in ionic liquids exhibited remarkably better extraction performance for lanthanides than that in octanol-dodecane (3:7 volume/volume) system. Lower HNO₃ concentration and short alkyl chain length of [C_nmim]⁺ were more favorable for removal of lanthanides. Besides, it was confirmed that isohexyl-BTP in ILs formed a 1:3 complex [Ln(BTP)₃(NO₃)_n]^(3-n)+ (n=0, 1) by slope anal. In addition, [C₂mim][NTf₂] preferred to extract lanthanides via a cation exchange mechanism at lower acidity, which was proved via UV-Vis measurement. It was speculated that extraction mechanism shifted from cation exchange to neutral species extraction with increase in HNO₃ concentration and alkyl chain length of [C_nmim]⁺ due to the H⁺ completion, NO^–₃ inhibition and hydrophobicity of IL.

Surface structures of binary mixture of ionic liquids was written by Nakajima, Kaoru;Nakanishi, Shunto;Lisal, Martin;Kimura, Kenji. And the article was included in Journal of Molecular Liquids in 2017.Synthetic Route of C18H31F6N3O4S2 This article mentions the following:

Surfaces of 11 equimolar mixtures of ionic liquids (ILs) consisting of 1-alkyl-3-methylimidazolium cations (from [C₂C₁Im] to [C₁₂C₁Im]) with anions (Cl, [BF₄], [TfO], [PF₆], [Tf₂N]) were observed using high-resolution Rutherford backscattering spectroscopy (HRBS). The elemental depth profiles of these IL mixtures were derived from the observed HRBS spectra through spectrum modeling. By comparing the observed depth profiles with those of pure ILs, the surface mole fractions of constituent ILs were estimated We found a general tendency that larger IL is enriched at the surface. The observed surface enrichment can be reasonably well reproduced by a simple thermodn. calculation based on the Sprow-Prausnitz equation. A slight deviation from the calculated result was ascribed to the nonideal behavior of the IL mixtures, which was neglected in the calculation In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Synthetic Route of C18H31F6N3O4S2).

A new approach to sepiolite dispersion by treatment with ionic liquids was written by de Lima, Juliana A.;Camilo, Fernanda F.;Faez, Roselena;Cruz, Sandra A.. And the article was included in Applied Clay Science in 2017.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The possibility of sepiolite disaggregation is a challenge to enhance significantly its performance and extend its application. In this direction, this work introduces the treatment of sepiolite (Sep) with three different ionic liquid (IL). The used ionic liquids were 1-methyl-3-butylimidazolium bis(trifluoromethanesulfonyl) imide (BMImTf₂N), 1-methyl-3-octylimidazolium bis(trifluoromethanesulfonyl) imide (OMImTf₂N) and 1-methyl-3- dodecylimidazolium bis(trifluoromethanesulfonyl) imide (DMImTf₂N). The influence on structural, thermal properties and morphol. in Sep treated with IL were evaluated using Fourier transform IR (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric anal. (TG), field emission SEM (FESEM), transmission electron microscopy (TEM), N₂ sorption measurements, ²⁹Si NMR (²⁹Si NMR) and zeta potential. Sepiolite structure was preserved for all the samples treated with ionic liquids FTIR and XRD results show that BMImTf₂N substitutes water mols. coordinated to Mg⁺² more efficiently. Thermogravimetric anal. indicated that the interaction between Sep and IL delayed the release of water. From these data, it was also possible to confirm the presence of 5 mass% of IL in all samples. FESEM and TEM images demonstrated more disaggregated Sep fibers with IL, especially the samples treated with BMImTf₂N. This fact is attributed to the immobilization of ionic liquid on Sep tunnels, which is coherent with ²⁹Si NMR analyses. The potential applications of these modified sepiolites are as reinforcing agent for polymers, template for nanostructured materials and support for catalysts.
