Corrosion inhibition of carbon steel in acidic environment by imidazolium ionic liquids containing vinyl-hexafluorophosphate as anion was written by Likhanova, Natalya V.;Olivares-Xometl, Octavio;Guzman-Lucero, Diego;Dominguez-Aguilar, Marco A.;Nava, Noel;Corrales-Luna, Monica;Mendoza, M. Consuelo. And the article was included in International Journal of Electrochemical Science in 2011.Formula: C9H15F6N2P This article mentions the following:

Five imidazolium-type ionic liquids, containing both N1-unsaturated chain and N3-long alkyl saturated chain as cations and hexafluorophosphate as anion (VImC_xPF₆, x = 4, 8, 12, 18 and 22), were evaluated as corrosion inhibitors for carbon steel SAE 1018 in 1.0 M H₂SO₄ solution The compounds presented relatively high inhibition efficiencies (∼81-96%) at 100 ppm as confirmed by weight loss tests and polarization curves. Synthesized inhibitors obeyed Langmuir adsorption and behaved as mixed type inhibitors, displaying phys. and chem. adsorption depending on the length of the carbon chain link to N3. Mossbauer anal. of corrosion products mainly determined the presence szomolnokite (FeSO₄.H₂O), whose content increased with aliphatic chain length suggesting that corrosion inhibition occurred by iron sulfate formation. The most effective compound (VImC₁₂PF₆) was the only that displayed the presence of alpha iron, iron hydroxide and rozenite (FeSO₄.4H₂O) as corrosion products. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Formula: C9H15F6N2P).

1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Formula: C9H15F6N2P

Pollinating insects such as honeybees play a critical role in maintaining the natural environment. The decline in honeybee populations is a global issue with significant repercussions with respect to the pollination of plants. The simultaneous expression of multifunctionality from synthesized ionic liquid gels (ILGs) for biotechnol. is presented in this study. We also demonstrate that, when mixed with photochromic organic compounds, ILGs display rapid color changes, similar to light-triggered camouflage, on living Musca domestica specimens. By further exploiting the physicochem. properties of ILGs, we were able to achieve effective pollen adsorption by ILG-functionalized Formica japonica specimens from Tulipa gesneriana flowers with high biocompatibility. In addition, a radiowave-controllable bio-inspired flying robot equipped with ILG-coated vertically aligned animal hairs could be used to successfully pollinate Lilium japonicum flowers. Such materially engineered artificial plant pollinators should lead to the development of high-performance robotics that can help counter the decline in honeybee populations.

A structure-activity relationship study of the affinity of selected imidazo[1,2-a]pyridine derivatives, congeners of zolpidem, for the ω₁-subtype of the benzodiazepine receptor was written by Lange, Jerzy;Karolak-Wojciechowska, Janina;Wejroch, Krystyna;Rump, Slawomir. And the article was included in Acta Poloniae Pharmaceutica in 2001.Electric Literature of C18H21N3 This article mentions the following:

A series of 6-substituted 2-aryl-N,N-dimethylimidazol[1,2-a]pyridine-3-acetamides, congeners of zolpidem and alpidem, was synthesized and tested in vitro for binding with the benzodiazepine receptor in the competition with ³H-zolpidem as an ω₁-selective radioligand. Mol. electrostatic potential (MEP) and the HOMO and LUMO energies were calculated for the compounds by semi-empirical quantum chem. methods. The lipophilicity parameter of the compounds, expressed as the logarithm of the octanol-water partition coefficient (log P), was calculated; alternatively, standard values of the Hansch hydrophobic substituent constants π were used. In agreement with earlier investigations on the benzodiazepine receptor ligands with a high preference for the ω₁-subtype, a quant. correlation of the biol. data with mol. parameters has revealed a significant dependence (r=0.954) of the binding affinity (IC₅₀) on the deepest MEP min., in this case associated with the amide carbonyl oxygen atom. The lipophilicity parameters were found to be of lower significance. In the experiment, the researchers used many compounds, for example, N,N-Dimethyl-1-(6-methyl-2-(p-tolyl)imidazo[1,2-a]pyridin-3-yl)methanamine (cas: 106961-33-5Electric Literature of C18H21N3).

Counterion-specific shale hydration inhibiting performance of vinylimdazolium ionic liquids was written by Yang, Lili;Kong, Dechang;Chang, Xiangyang;Jiang, Guancheng;Ao, Tian;Xie, Chunlin;Kinkeyi Moukoko, Aurchy Dauriant;Ma, Jiaying. And the article was included in Journal of Molecular Liquids in 2021.Recommanded Product: 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) This article mentions the following:

The role of cation and the influence of the cation alkyl chain length of vinylimdazolium-based ionic liquid (IL) were studied previously to develop high-performance shale inhibitor for application in water-based drilling fluids (WBDFs). Results demonstrate that they have a considerable effect on the inhibition performance. However, the physicochem. properties can be tuned by changing the cation/anion combination. Therefore, the influence of anion type on the inhibiting performance must be investigated. In this study, we selected several vinylimdazolium-based ILs with different anions, such as bromide (Br-), tetrafluoroborate (BF-4), hexafluorophosphate (PF-6), and bis(trifluoromethylsulfonyl) (TFSI-). The size, solubility, hydrophilicity, and interaction in-between were tuned accordingly by changing the anion species. Results from linear swelling height, hot rolling recovery, and rheol. measurements show that the IL with bromide anion has the most outstanding shale inhibiting performance. The anions influence the inhibitory performance of ILs in a distinct manner from cations by measuring the properties of Na-Bent dispersions added with different anion-based ILs. The former produces different abilities to suppress elec. double layers and decreases the interlayer distance, whereas the latter mainly affects the interlayer distance. Despite different hydrophilic/hydrophobic properties, they have similar performance to inhibit the crystalline hydration and swelling. This condition is probably because they have a common cation that dominates the process of entering the interlayer void and narrowing interlayer spacing. Many hydrophilic ILs with anion Br- or BF-4 have the capacity to strongly resist the repel interaction between clay particles and prompt aggregation, leading to better inhibitory performance. Combined with the previous result, cations and anions affect the IL inhibiting ability although their underlying mechanism is different. Thus, this work explored the relationship between inhibiting performance and IL moiety. The findings provide consolidate theor. foundation for developing shale inhibitors for WBDFs.
