《Ru-Pd Thermoresponsive Nanocatalyst Based on a Poly(ionic liquid) for Highly Efficient and Selectively Catalyzed Suzuki Coupling and Asymmetric Transfer Hydrogenation in the Aqueous Phase》 was written by Li, Xinjuan; Sun, Yanping; Wang, Shangyue; Jia, Xianbin. Computed Properties of C4H6N2 And the article was included in ACS Applied Materials & Interfaces in 2020. The article conveys some information:

The development of intelligent polymeric materials to precisely control the catalytic sites of heterogeneous catalysts and enable highly efficient catalysis of a cascade reaction is of great significance. The use of a polymer ionic liquid (PIL) containing 2 different anions facilitates the preparation of Ru-Pd catalysts with controllable phase transition temperatures and hydrophilic and hydrophobic surfaces. The combined multifunctionality, synergistic effects, micellar effects, aggregation effects, and temperature responsiveness of the nanocatalyst render it suitable for promoting selectively catalyzed Suzuki coupling and asym. transfer hydrogenation in H2O. Above the lower critical solution temperature (LCST) of the catalyst, it catalyzes only the coupling reaction with a high turnover number (TON) of ≤999.0. Below the LCST, the catalyst catalyzes only the asym. transfer hydrogenation with good catalytic activity and enantioselectivity. It is important that the catalyst can be simply and effectively recovered and recycled ≥10 times without significant loss of catalytic activity and enantioselectivity. This study also highlights the superiority of multifunctional heterogeneous catalysts based on PILs, which not only overcome limitations associated with low activity of heterogeneous catalysts but also realize selective reactions according to a temperature change, thereby improving the reactivity and enantioselectivity in multiple organic transformations. In the experiment, the researchers used many compounds, for example, 1-Methyl-1H-imidazole(cas: 616-47-7Computed Properties of C4H6N2)

《Zwitterions as novel phase forming components of aqueous biphasic systems》 was written by Basaiahgari, Anusha; Yadav, Sandeep Kumar; Gardas, Ramesh L.. Application of 616-47-7This research focused onZwitterion aqueous biphasic system phase forming component. The article conveys some information:

A novel class of aqueous biphasic systems (ABS) formed by zwitterions (ZI) has been investigated in the present work. A series of water soluble ZIs have been synthesized using triethylamine, N-Methylimidazole, N-Vinylimidazole, pyridine, N-Methylpyrrolidine, N-Ethylpiperidine and 1,4 butane sultone. The synthesized ZIs were explored for their ability to form biphasic systems in combination with aqueous inorganic salt solutions of K3PO4, K2HPO4 and K2CO3. The phase diagrams for all systems have been constructed through cloud point titration method at 298.15 K and atm. pressure. The phase behavior of ZI based ABS have been analyzed to understand the structural effects of ZIs as well as the effect of nature of salt used on the overall phase formation. Further the temperature dependence of the ZI based ABS was also explored by studying the phase behavior at variable temperatures of 298.15, 308.15 and 318.15 K. In order to estimate the applicability of proposed ZI based ABS, extraction experiments have been performed for an alkaloid i.e. caffeine for all synthesized ZIs with K3PO4 and at 298.15 K. ZI based ABS have been found to be capable of single step extraction of caffeine similar to IL based ABS thus providing the possibilities to explore these ZI based ABS as efficient extraction and separation systems.

In 2019,Journal of Applied Polymer Science included an article by Huo, Pengfei; Xun, Zhiyu; Ni, Shoupeng; Liu, Yang; Wang, Guibin; Gu, Jiyou. COA of Formula: C4H6N2. The article was titled 《Crosslinked quaternized poly(arylene ether sulfone) copolymer membrane applied in an electric double-layer capacitor for high energy density》. The information in the text is summarized as follows:

The low energy d. of supercapacitors, especially supercapacitors based on aqueous electrolytes, is the main factor limiting their application, and the energy d. is closely related to the operating potential window of the supercapacitor. The polymer electrolyte is the main contributor to the safe operation and good ion conductivity of the supercapacitor. In this study, a crosslinked quaternized poly(arylene ether sulfone) (PAES) membrane was prepared via crosslinking during membrane formation with a thermal-only treatment and applied in an elec. double-layer capacitor (EDLC). The pre-prepared PAES membrane formed a polymer electrolyte with 1 mol/L Li2SO4 and was then fabricated into an EDLC single cell. The properties of both the membrane and ELDC were investigated. The preferred cPAES-N-0.2 polymer electrolyte showed an ionic conductivity of 1.18 mS/cm. The optimized EDLC exhibited a single-electrode gravimetric capacitance of 104.92 F/g at a c.d. of 1.0 A/g and a high operating potential window (1.5 V); it, thereby, achieved a high energy d. of 8.20 W h/kg. The EDLC also exhibited excellent cycling properties over 3000 charge-discharge cycles. The crosslinked structures promoted the tensile strength and thermal stability of the PAES membranes; this was accompanied by a slight decrease in the ionic conductivity In the part of experimental materials, we found many familiar compounds, such as 1-Methyl-1H-imidazole(cas: 616-47-7COA of Formula: C4H6N2)

Product Details of 616-47-7In 2019 ,《Self-assembled structure and dynamics of imidazolium-based protic salts in water solution》 was published in Physical Chemistry Chemical Physics. The article was written by Zhu, Haijin; Vijayaraghavan, R.; MacFarlane, Douglas R.; Forsyth, Maria. The article contains the following contents:

Protic ionic liquids containing cations with long alkyl chains can form self-assembled micelles, vesicles, microemulsions, and lyotropic liquid crystal structures in water, acid water or THF, etc. As a result of this unique property, they are regarded as a novel category of amphiphiles, and are gaining importance in the field of colloid and interface chem. The critical micelle concentration (CMC) of protic salts, e.g., alkyl-ammonium nitrates in water, was found to increase with decreasing chain length. It is generally believed that a long alkyl chain length is essential for the formation of self-assembled structures. So far, no self-assembled structure has been reported for protic ionic liquids with an alkyl chain length of n < 4. This paper reports on the structure and dynamics of two imidazolium based protic organic salts with no alkyl chain or a Me group (n = 1) attached to the cation in water solution, determined through a detailed anal. of NMR spectra and pulsed-field gradient NMR data. We demonstrate that these imidazolium cations with no or a short alkyl chain (n = 1) can form a self-assembled clustering structure in water solution, which has a strong influence on the diffusion behavior of imidazolium mol. ions. It is speculated that this self-assembled structure is likely to be present in other similar solutions of ionic liquids with short alkyl chains.1-Methyl-1H-imidazole(cas: 616-47-7Product Details of 616-47-7) was used in this study.

Quality Control of 1-Methyl-1H-imidazole And the article was included in Journal of Chemical Education in 2020. The article conveys some information:

A review. The complexity of the world’s current grand challenges demands interdisciplinary approaches. The education of future scientists must cross the silos of the traditional disciplines; however, there is still a strong reluctance to tear such walls down. Here, we describe an integrative chem. biol. course focused on epigenetics that strives to bring research culture to chem. and biol. Master’s students. The course, which has been successfully implemented for the past two years, combines three modules: lectures, discovery-based research lab, and science communication. Importantly, the outline of our course design could be easily adapted to different fields, improving the synergy between research and teaching in our universities.

In 2019,Journal of Physical Chemistry B included an article by Amoruso, Giordano; Taylor, Victoria C. A.; Duchi, Marta; Goodband, Emma; Oliver, Thomas A. A.. Recommanded Product: 1-Methyl-1H-imidazole. The article was titled 《Following Bimolecular Excited-State Proton Transfer between Hydroxycoumarin and Imidazole Derivatives》. The information in the text is summarized as follows:

The ultrafast dynamics of a bimol. excited-state proton transfer (ESPT) reaction between the photoacid 7-hydroxy-4-(trifluoromethyl)-1-coumarin (CouOH) and 1-methylimidazole (MI) base in aprotic chloroform-d1 solution were investigated using ultrafast transient IR (TRIR) and transient absorption (TA) spectroscopies. The excited-state lifetime of the photoacid in solution is relatively short (52 ps), which at the millimolar photoacid and base concentrations used in our study precludes any diffusion-controlled bimol. ESPT reactions. This allows the prompt ESPT reaction between hydrogen-bonded CouOH and MI mols. to be studied in isolation and the “”contact”” ESPT dynamics to be unambiguously determined Our time-resolved studies reveal that ultrafast ESPT from the CouOH moiety to hydrogen-bonded MI mols. occurs within ∼1 ps, tracked by unequivocal spectroscopic signatures of CouO-* photoproducts that are formed in tandem with HMI+. Some of the ESPT photoproducts subsequently π-stack to form exciplexes on a ∼35 ps time scale, minimizing the attractive Coulombic forces between the oppositely charged aromatic mols. For the concentrations of CouOH and MI used in our study (up to 8 mM), we saw no evidence for excited-state tautomerization of coumarin anions.

And the article was published in Journal of Physical Chemistry B in 2019. Reference of 1-Methyl-1H-imidazole The author mentioned the following in the article:

The unique characteristics of an acetic acid/1-methylimidazole (1-MI) mixture, showing higher elec. conductivity than either neat acetic acid or neat 1-MI, yet consisting of elec. neutral mols., are reported. We have applied soft X-ray spectroscopy to reveal the electronic states of acetic acid in the acetic acid/1-MI mixture at various mole fractions of acetic acid (χHOAc). The results show that the amount of acetic acid monomer increases in the region of especially high elec. conductivity and the amount of complex of acetic acid and 1-MI formed by sharing MOs increases in the low elec. conductivity region. There is a little amount of acetic acid monomer in the low elec. conductivity region because the complex inhibits acetic acid from creating its monomer. These results suggest the possibility that the acetic acid monomer is related to elec. conduction.

The author of 《Position-specific 15N isotope analysis in organic molecules: A high-precision 15N NMR method to determine the intramolecular 15N isotope composition and fractionation at natural abundance》 were Joubert, Valentin; Silvestre, Virginie; Lelievre, Maxime; Ladroue, Virginie; Besacier, Fabrice; Akoka, Serge; Remaud, Gerald S.. And the article was published in Magnetic Resonance in Chemistry in 2019. Application of 616-47-7 The author mentioned the following in the article:

The position-specific 15N isotope content in organic mols., at natural abundance, is for the first time determined by using a quant. methodol. based on 15N NMR spectrometry. 15N NMR spectra are obtained by using an adiabatic “”Full-Spectrum”” INEPT sequence in order to make possible 15N NMR experiments with a high signal-to-noise ratio (>500), to reach a precision with a standard deviation below 1% (0.1%). This level of precision is required for observing small changes in 15N content associated to 15N isotope effects. As an illustration, the measurement of an isotopic enrichment factor ε for each 15N isotopomer is presented for 1-methylimidazole induced during a separation process on a silica column. The precision expressed as the long-term repeatability of the methodol. is good enough to evaluate small changes in the 15N isotope contents for a given isotopomer. As observed for 13C, inverse and normal 15N isotope effects occur concomitantly, giving access to new information on the origin of the 15N isotope effects, not detectable by other techniques such as isotope ratio measured by Mass Spectrometry for which bulk (average) values are obtained.

《Ion Vacancies and Transport in 1-Methylimidazolium Triflate Organic Ionic Plastic Crystal》 was written by Zhu, Haijin; Forsyth, Maria. Quality Control of 1-Methyl-1H-imidazole And the article was included in Journal of Physical Chemistry Letters in 2020. The article conveys some information:

Organic ionic plastic crystals (OIPCs) are an important family of materials that have shown exciting possibilities as solid electrolytes for lithium ion batteries and other electrochem. devices. In this study we demonstrate for the first time that, although the X-ray shows sharp diffraction peaks, both cation and anion clearly exhibit significant ion diffusion in solid phase I. Two phases with ion diffusivities differing by 2 orders of magnitude can be identified. The populations of the cation and anion in both phases are found to be unequal, hinting at the existence of (neg. charged) cation vacancies in the plastic crystal phase and a pos. charged grain boundary phase. These interesting properties of ion vacancies and unequal populations of cation and anion are likely to be ubiquitous in other OIPCs, and it is of paramount importance to be aware of these features to correctly understand the structure-property relationships of this important material family.
