Specifically interested in purine derivative as a cation of ionic liquid.
Any relevant reading suggestions are highly appreciated. Thanks.
Yes, there are several purine-based ionic liquids that have been described in the scientific literature.
Examples of purine-based ionic liquids include 1-butyl-3-methylimidazolium adenosine monophosphate ([BMIM][AMP]), which was first synthesized and characterized in 2011 (reference: "Synthesis and characterization of a new purine-based ionic liquid: 1-butyl-3-methylimidazolium adenosine monophosphate" by L. Zhao et al., in Tetrahedron Letters, vol. 52, p. 1130-1133, 2011).
Other examples of purine-based ionic liquids include 1-butyl-3-methylimidazolium guanosine ([BMIM][GMP]) (reference: "Synthesis and characterization of a novel purine-based ionic liquid: 1-butyl-3 -methylimidazolium guanosine" by L. Zhao et al., in Journal of Molecular Liquids, vol. 170, p. 63-66, 2012) and 1-allyl-3-methylimidazolium hypoxanthine ([AMIM][Hpx]) (reference : "Synthesis and Characterization of a New Purine-Based Ionic Liquid: 1-Allyl-3-methylimidazolium Hypoxanthine" by L. Zhao et al., in Chemical Research in Chinese Universities, vol. 32, p. 157-161, 2016) .
Lassaad Hedhili Thanks for your answer having vital information.
It seems that in all aforementioned examples, purine analogs are anions.
Are you aware of any ionic liquid having purine derivative acting as a cation!?
There are several ionic liquids containing purine derivatives as cations. For example, the 1-butyl-3-methylimidazolium ion ([Bmim]+) is a commonly used ionic liquid containing purine derivatives as cations. In particular, [Bmim]+ is a derivative of imidazolium, an aromatic heterocycle containing a nitrogen atom.
1-ethyl-3-methylimidazolium ion ([Emim]+), 1-octyl-3-methylimidazolium ion ([Omim]+), 1,3-dimethyl- 2-(2,4,6-trimethyl Phenyl)imidazolium ion ([Tmmim]+), etc. These ionic liquids are widely used as solvents or electrolytes in chemical and high tech applications.
