CO2 Responsive Imidazolium-Type Poly(Ionic Liquid) Gels was written by Zhang, Jing;Xu, Dan;Guo, Jiangna;Sun, Zhe;Qian, Wenjing;Zhang, Ye;Yan, Feng. And the article was included in Macromolecular Rapid Communications in 2016.Reference of 915358-85-9 This article mentions the following:
Poly(ionic liquid) (PIL) gels with CO2 stimulus responsiveness were synthesized through the copolymerization of an imidazolium-type ionic liquid monomer with 2-(di-Me amino) Et methacrylate. Upon bubbling with CO2 gas, the prepared PIL solution is converted to a transparent and stable gel, which can be turned back to the initial solution state after N2 bubbling. The reversible sol-gel phase transition behavior is proved by the reversible values of viscosity and ionic conductivity The possible mechanism for such a reversible sol-gel phase transition is demonstrated by NMR, conductivity, and rheol. measurements. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Reference of 915358-85-9).
1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Reference of 915358-85-9
