And the article was included in New Journal of Chemistry in 2017.Recommanded Product: 1-Octyl-1H-imidazole This article mentions the following:
To gain more insights into the factors acting on the stability of complexes formed by pillar[5]arenes, we investigated the interaction of dimethoxypillar[5]arene with some 1-(n-alkyl)-3-(9-anthracenylmethyl)-imidazolium based organic salts. In particular, we used salts differing in not only the anion nature ([Cl–], [BF4–], [NTf2–] and [SbF6–]) and alkyl chain length (Bu, octyl and dodecylimidazolium derivatives), but also the presence of a hydrogenated or fluorinated tail (octyl and perfluorooctylimidazolium derivatives). Host-guest systems were analyzed in solution, solid state and gas phase, using a combined approach of different techniques like fluorescence, 1H NMR, ESI-MS, DSC and DFT calculations Data collected show that the complex stability is heavily affected by solvent nature. Furthermore, solvent being the same, it increases with the decrease of the alkyl chain length and the anion coordination ability. The joint information obtained from 1H NMR and DFT calculations allows drawing a picture of the complex geometry. On the other hand, fluorescence investigation on the solid state evidences the occurrence of an aggregation enhanced emission process for these systems. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Recommanded Product: 1-Octyl-1H-imidazole).
1-Octyl-1H-imidazole (cas: 21252-69-7) 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 has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.Recommanded Product: 1-Octyl-1H-imidazole
