And the article was included in ACS Applied Materials & Interfaces in 2016.Application In Synthesis of 1-Octyl-1H-imidazole This article mentions the following:

To expand the application of solid-state dye-sensitized solar cells (ssDSSCs) to low temperatures, it is necessary to develop new solid electrolytes with low glass transition temperature (T_g). The T_g is regulated by varying the length of alkyl chain that is connected with the nitrogen atom in the imidazolium ring linked to the polyhedral oligomeric silsesquioxane (POSS). The T_g as low as -8.8 °C is achieved with the POSS grafted with methyl-substituted imidazolium. The effect of alkyl group on the conductivity, T_g, and photovoltaic performance has also been investigated. The conductivity and power conversion efficiency increase with the alkyl length, while the T_g first increases and then decreases with the alkyl length. Among the synthesized POSS-based ionic conductors, the POSS grafted with the methyl-substituted imidazolium yields the highest power conversion efficiency of 6.98% at RT due to its highest conductivity, and the efficiency (6.52%) is still good at -4 °C, as its T_g (-8.8 °C) is lower than the working temperature (-4 °C). This finding suggests that the POSS-based solid electrolyte is promising for subzero-temperature applications of ssDSSCs. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Application In Synthesis of 1-Octyl-1H-imidazole).

Electrochemical behavior of 4-nitroimidazole and 2-methyl-5-nitroimidazole. Autoprotonation of anion radical and redox-catalyzed reduction of the supporting electrolyte cation was written by Roffia, S.;Gottardi, C.;Vianello, E.. And the article was included in Journal of Electroanalytical Chemistry and Interfacial Electrochemistry in 1982.Safety of 1-Methyl-4-nitroimidazole This article mentions the following:

The electrochem. behavior of the title imidazoles (HRNO₂) was studied in DMF and MeCN by polarog., cyclic voltammetry and controlled-potential electrolysis and coulometry. The above nitroimidazoles present similar behavior, displaying 2 reduction waves paralleled by 2 reduction peaks in linear sweep voltammetry. The 1st peak is irreversible up to a sweep rate of 250 V s^-1, while the 2nd one appears voltammetry. The exptl. data in the 1st process are consistent with the hypothesis that the irreversibility of the 1st wave is due to a rapid decay of the primary anion radical of HRNO₂ because of a fast protonation reaction by the starting nitroimidazole, with the formation of the conjugate base RNO₂^– and of the neutral radical of HRNO₂H. This last radical gives rise, as final reduction product, to the hydroxylamino derivative, the necessary protons being supplied by the starting HRNO₂. The 2nd process is attributable to the reduction of RNO₂^– to radical dianion of RNO₂. The complete mechanism is discussed in detail. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Safety of 1-Methyl-4-nitroimidazole).

Cell Permeable Imidazole-Desferrioxamine Conjugates: Synthesis and In Vitro Evaluation was written by Pramanik, Shreya;Chakraborty, Saikat;Sivan, Malavika;Patro, Birija S.;Chatterjee, Sucheta;Goswami, Dibakar. And the article was included in Bioconjugate Chemistry in 2019.Reference of 21252-69-7 This article mentions the following:

Desferrioxamine (DFO), a clin. approved iron chelator used for iron overload, is unable to chelate labile plasma iron (LPI) because of its limited cell permeability. Herein, alkyl chain modified imidazolium cations with varied hydrophobicities have been conjugated with DFO. The iron binding abilities and the antioxidant properties of the conjugates were found to be similar to DFO. The degree of cellular internalization was much higher in the octyl-imidazolium-DFO conjugate (IV) compared with DFO, and IV was able to chelate LPI in vitro. This opens up a new avenue in using N-alkyl imidazolium salts as a delivery vector for hydrophilic cell-impermeable drugs. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Reference of 21252-69-7).

Revealing the roles of hydrogen bond and Al₂Cl^–7 anion species and kinetics for ionic liquid catalyzed transesterification of ethylene carbonate with methanol was written by Wang, Gang;Zhao, Shirun;Yao, Haoyu. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2023.Category: imidazoles-derivatives This article mentions the following:

The co-production of di-Me carbonate (DMC) and ethylene glycol (EG) from the transesterification of ethylene carbonate (EC), which is synthesized from CO₂ and ethylene oxide, with methanol has received researchers′ attention. The interaction between cation and methanol via hydrogen bond and activation of carbonyl group in EC (or 2-hydroxyethyl Me carbonate, HEMC) by metal chloride-contained anion were identified to show synergistic effects on catalytic transesterification. Not AlCl₄^– but Al₂Cl₇^– anion species in AlCl₃-based IL exhibited activity in this transesterification, and the content of Al₂Cl₇^– species was observed to show linear relationship with the transformative rates of both EC and HEMC. The kinetic studies also elucidated that the rates of both EC (or HEMC) and methanol are first-order dependent on their concentrations, and the formation of HEMC intermediate was the kinetic-relevant step with the activation barrier of 92 kJ/mol. As a result, the yield and selectivity of DMC (or EG) could reach up to around 95 % and 97 % with catalysis of [MDMIM]Cl/AlCl₃ with AlCl₃ molar fraction of 0.67 after 12 h reaction at 140 °C, which showed higher performance than any other tested metal chloride-based IL. Besides, no decay in catalytic activity and selectivity of this IL was observed after 10 times′ recycling.

Production of silk fibroin nanoparticles using ionic liquids and high-power ultrasounds was written by Abel Lozano-Perez, Antonio;Montalban, Mercedes Garcia;Aznar-Cervantes, Salvador David;Cragnolini, Francesca;Cenis, Jose Luis;Villora, Gloria. And the article was included in Journal of Applied Polymer Science in 2015.Reference of 79917-89-8 This article mentions the following:

Biopolymeric nanoparticles have attracted great research interest in the last few years due to their multiple applications. This article describes how high-power ultrasounds are capable of enhancing the dissolution process of silk proteins in ionic liquids (ILs) and how silk fibroin nanoparticles (SFNs) can be obtained directly from the silk/ionic liquid solution (SIL) by rapid desolvation in polar organic solvents. The silk fibroin integrity is highly preserved during the dissolution process, as confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of the SIL. These regenerated SFNs are insoluble in water and other common organic solvents and are indistinguishable from the classical SFNs with respect to their diameter (180 ± 5 nm), Zeta potential (-25 ± 3 mV), high degree of β-sheet and low cytotoxicity. Large amounts of silk can be turned into biomaterials directly from the SIL solution for use in a wide range of applications, while the ILs can be recovered from the coagulant solution under reduced pressure and reused without loss of their solvent properties. © 2014 Wiley Periodicals, Inc.

Influence of Ionic Liquid on Recombination and Regeneration Kinetics in Dye-Sensitized Solar Cells was written by Li, Feng;Jennings, James Robert;Wang, Xingzhu;Fan, Li;Koh, Zhen Yu;Yu, Hao;Yan, Lei;Wang, Qing. And the article was included in Journal of Physical Chemistry C in 2014.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride This article mentions the following:

Nonvolatile electrolyte solutions are necessary for dye-sensitized solar cells (DSCs) with good long-term stability. Such electrolytes usually contain room-temperature ionic liquids (RTILs) and consequently possess higher viscosity and ionic strength than the volatile electrolytes used in current champion cells. In this study, we systematically investigated the effect of an RTIL additive on the performance of DSCs employing either a classical Ru-complex dye or a recently developed organic D-A-π-A dye, in combination with either I^–/I₃^– or [Co(bpy)₃]^2+/3+ as redox mediator. Using impedance spectroscopy and transient absorption measurements under various background illumination intensities, recombination and regeneration kinetics were examined Recombination is accelerated in the I^–/I₃^– devices upon addition of RTIL, regardless of the dye used, but it is retarded in the [Co(bpy)₃]^2+/3+ devices. Addition of RTIL slowed regeneration in I^–/I₃^– devices for both sensitizers, marginally accelerated it for [Co(bpy)₃]^2+/3+ with the Ru-complex dye, and did not significantly affect it for [Co(bpy)₃]^2+/3+ with the D-A-π-A dye. We show that these findings cannot be explained by diffusion limitations caused by increased solution viscosity or by a shift in the TiO₂ conduction band relative to the electrolyte redox level. These findings should be useful for future optimization of RTIL-based DSCs. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride).

Precise synthesis of amphiphilic diblock copolymers consisting of various ionic liquid-type segments and their influence on physical gelation behavior in water was written by Yokota, Daichi;Kanazawa, Arihiro;Aoshima, Sadahito. And the article was included in RSC Advances in 2020.Related Products of 35487-17-3 This article mentions the following:

Appropriately designed amphiphilic diblock vinyl ether (VE) copolymers consisting of an ionic liquid-type segment and a hydrophobic segment were demonstrated to undergo phys. gelation in water at extremely low concentrations The precursor diblock copolymers were synthesized by the living cationic polymerization of 2-chloroethyl VE with a hydrophobic VE through an appropriately designed initiating system such as optimized temperature and catalyst. A relatively high temperature such as 20°C was important for controlled polymerization of octadecyl VE. Ionic liquid moieties with imidazolium salt structures were subsequently introduced into the side chains of the diblock copolymers via chem. modifications of the 2-chloroethyl groups. The phys. gelation behavior of the obtained diblock copolymers was examined in water, with a particular focus on the influence of the hydrophobic VEs, the hydrophilicity of the counteranions and the substituents on the ionic liquid-type segments, and the length of each segment. Based on this systematic investigation, phys. gelation at concentrations as low as 0.2 wt% was achieved with diblock copolymers with a suitable balance of these factors.
