Europium-based ionic liquids as luminescent soft materials was written by Tang, S.;Babai, A.;Mudring, A.-V.. And the article was included in Angewandte Chemie, International Edition in 2008.SDS of cas: 79917-89-8 This article mentions the following:
Low melting, highly luminescent: [C3mim][Eu(Tf2N)4] (1), [C4mim][Eu(Tf2N)4], and [C4mpyr]2[Eu(Tf2N)5] (Tf2N = bis(trifluoromethanesulfonyl)amide; C3mim = 1-propyl-3-methylimidazolium; C4mim = 1-butyl-3-methylimidazolium; C4mpyr = 1-butyl-1-methylpyrrolidium) are the 1st lanthanide ionic liquids that do not need stabilization of the liquid state by neutral coligands. They show excellent photophys. properties, such as long lifetimes of luminescence at large EuIII concentration, small line width, and high color purity (see emission spectrum of 1 and photograph of a sample under UV light). In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8SDS of cas: 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).SDS of cas: 79917-89-8
