Interesting phase behaviors and ion-conducting properties of dicationic N-alkylimidazolium tetrafluoroborate salts was written by Chae, Hyunho;Lee, Yong-Hoon;Yang, Minyong;Yoon, Won-Jin;Yoon, Dong Ki;Jeong, Kwang-Un;Song, Yeon Hwa;Choi, U. Hyek;Lee, Minjae. And the article was included in RSC Advances in 2019.COA of Formula: C11H20N2 This article mentions the following:
A series of dicationic imidazolium bis(tetrafluoroborate) salts I (R = Bu, n-hexyl, n-octyl, etc.) was newly synthesized, and their phase transition behaviors were correlated with thermal, scattering, optical and conductivity results. The bis-imidazolium salts I having side-chain lengths of C6-C10 showed plastic crystal mesophases, while a liquid crystal mesophase was formed in the bis-imidazolium salts with long side-chains (C11 and C12). Soft plastic and liquid crystalline phases were also confirmed by wide-angle X-ray diffraction. For the bis-imidazolium salts I exhibiting a plastic crystal mesophase, the ionic conductivity suddenly increased at the melting temperature However, the bis-imidazolium salts with long side-chains I showed a slope increase during the liquid crystal-liquid crystal transition. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7COA of Formula: C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) 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 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.COA of Formula: C11H20N2
