Heterogeneous polarity and surface acidity of silica-organic materials with fixed 1-n-propyl-3-methylimidazolium chloride as probed by solvatochromic and fluorescent dyes was written by Khristenko, I. V.;Panteleimonov, A. V.;Iliashenko, R. Yu.;Doroshenko, A. O.;Ivanov, V. V.;Tkachenko, O. S.;Benvenutti, E. V.;Kholin, Yu. V.. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2018.Recommanded Product: 79917-89-8 This article mentions the following:

A new silica-organic hybrid material with fixed ionic liquid 1-n-propyl-3-methylimidazolium chloride has been synthesized by the sol-gel method. Its sp. surface area is 22 m² g^-1, average pore diameter is 8 nm and pore volume is 0.05 cm³ g^-1. According to the results of ¹³C NMR spectroscopy, the fixed 1-n-propyl-3-methylimidazolium cationic group is bound with the siloxane framework via one Si-C covalent bond. Properties of the new material were compared with that of its analog, silica with the same modifier covalently grafted at the surface. With the use of the ²⁹Si NMR spectroscopy it was clearly indicated that at the surfaces of both materials silanol groups dominate among all silicon containing groups. The surface polarity was characterized by probing the materials with the solvatochromic Reichardt’s dyes, and the heterogeneous polarity of the near-surface layers has been detected. The values of the normalized Dimroth-Reichardt parameter for three surface regions of different polarities are 0.9-1.0, 0.65 and 0.4. The presence of rather acidic surface silanol groups revealed from probing these materials with solvatochromic dyes was verified with the application of acid-base fluorescent dyes of 2,5-diaryl-1,3-oxazole series having pK_a 4.5-4.8 in ethanol/water medium. The fluorescence spectroscopy experiments have proved unambiguously that surface silanol groups predetermine the possibility of coexistence of the conjugated Bronsted basic and acidic forms of the oxazolic dyes in the near-surface layers. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Recommanded Product: 79917-89-8).

Synthesis, DNA binding, cytotoxic properties, and structure-activity relationship of a series of head to tail, and tail to tail linked imidazole- and pyrrole-containing analogs of distamycin with N-terminal benzoic acid mustard groups was written by Lee, Moses;Garbiras, Bonnie J.;Young, Chad;Blair, Brian;Wyatt, Michael D.;Hartley, John A.. And the article was included in Medicinal Chemistry Research in 1994.Safety of 1-Methyl-4-nitroimidazole This article mentions the following:

The synthesis and biol. evaluation of the titled compounds are described. Results from an ethidium displacement assay showed that all of these compounds bound strongly to the DNAs studied, and they generally interacted equally well or slightly more strongly to poly(dA-dT) than to poly(dG-dC). Introduction of an aliphatic linker in the head to tail (N to C) compounds significantly decreased their cytotoxicities compared to the oligoimidazole analogs. In the tail to tail (C to C) series of compounds the 1:1 dimeric compounds showed significant improvement in cytotoxicities over their monomeric counterparts, presumably due to their increased ability to produce interstrand crosslinks in the minor groove. The 2:2 dimeric compounds were only slightly more cytotoxic than their monomeric congeners even though their crosslinking abilities were enhanced. This may be due to their poor solubilities in water. There were no significant differences in the cytotoxicities between the tail to tail linked pyrrole- and imidazole-containing compounds In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Safety of 1-Methyl-4-nitroimidazole).

1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring.

Imidazole derivatives are effective ligands for promoting the [Ru₃(CO)₁₂]-catalyzed hydroesterification of alkenes using formates. Extensive ligand screening was performed to identify 2-hydroxymethylated imidazole as the optimal ligand. Neither carbon monoxide gas nor a directing group was required, and the reaction also showed a wide substrate generality. The Ru-imidazole catalyst system also promoted intramol. hydrocarbamoylation to afford lactams. A Ru-imidazole complex was unambiguously analyzed by x-ray crystallog., and it had a trinuclear structure derived from one [Ru₃(CO)₁₂] and two ligands. This complex was also successfully used for hydroesterification. The mechanism was examined in detail by using D- and ¹³C-labeled formates, indicating that the hydroesterification reaction proceeds by a decarbonylation-recarbonylation pathway.

And the article was included in Industrial & Engineering Chemistry Research in 2021.Electric Literature of C7H13ClN2 This article mentions the following:

The melt-phase polymerization of bisphenol A (BPA) and di-Ph carbonate (DPC) catalyzed by alk. metal catalysts produces polycarbonates with high branching, which impairs the product’s properties during weather resistance, ductility, and rheol. The use of an imidazolium-type catalyst can result in a reduced amount of branching relative to the benchmark Cs₂CO₃ catalyst. Modification of the imidazolium structure, especially by introducing a substitution at the C2 position, definitely improves the catalyst performance in enhancing the catalyst stability and reducing the branching level in the polycarbonate product. For the best catalyst identified (1,3-Ad₂-2-Ph-Im-BPA), we have shown that at a DPC/BPA ratio of 1.075 and a catalyst loading of 7 ppm, the specifications can be met at the laboratory scale: polymerization time = 125 min, M_n = 11.0 K, OH = 660 ppm, branching = 460 ppm (鈭?5% reduction relative to the Cs₂CO₃ benchmark), and yellowness index = 6.3.

Substituent Effect of Imidazolium Ionic Liquid: A Potential Strategy for High Coulombic Efficiency Al Battery was written by Yang, Congrong;Wang, Suli;Zhang, Xiaoming;Zhang, Qiang;Ma, Wenjia;Yu, Shansheng;Sun, Gongquan. And the article was included in Journal of Physical Chemistry C in 2019.Name: 1-Methyl-3-propylimidazolium Chloride This article mentions the following:

The chem. structure-effect relationship between imidazolium ion liquid and the properties of electrolyte or Al battery is first completely revealed. First, it is proved that there indeed exsits an interaction between imidazolium cation and chloroaluminate anions (active ions, Al₂Cl₇^– and AlCl₄^–), blocking their reaction in the anode or pos. electrode. Second, by introducing the substituent effect, which could enhance the steric hindrance and change the detailed electronic distribution of imidazolium cations, the intermol. force between imidazolium cations and chloroaluminate anions is effectively weakened. As a result, the electrodeposition achievement, electrodeposition/electrostripping reversibility of aluminum, and intercalation/deintercalation capacity of AlCl₄^– in the pos. electrode are significantly improved. Therefore, the as-assembled battery with AlCl₃/[MPIM]Cl electrolyte shows an 鈭?00% CE. This work provides a potential approach on how to enhance the performance of Al battery by designing the ionic liquid structure.

Inelastic neutron scattering study on boson peaks of imidazolium-based ionic liquids was written by Kofu, Maiko;Inamura, Yasuhiro;Moriya, Yosuke;Podlesnyak, Andrey;Ehlers, Georg;Yamamuro, Osamu. And the article was included in Journal of Molecular Liquids in 2015.Reference of 79917-89-8 This article mentions the following:

Low energy excitations of 1-alkyl-3-methylimidazolium ionic liquids (ILs) have been investigated by means of neutron spectroscopy. In the spectra of inelastic scattering, a broad excitation peak referred to as a “boson peak” appeared at 1-3 meV in all of the ILs measured. The intensity of the boson peak was enhanced at the Q positions corresponding to the diffraction peaks, reflecting the in-phase vibrational nature of the boson peak. Furthermore the boson peak energy (E_BP) was insensitive to the length of the alkyl-chain but changed depending on the radius of the anion. From the correlation among E_BP, the anion radius, and the glass transition temperature T_g, we conclude that both E_BP and T_g in ILs are predominantly governed by the inter-ionic Coulomb interaction which is less influenced by the alkyl-chain length. We also found that the E_BP is proportional to the inverse square root of the mol. weight as observed in mol. glasses. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
