Room-Temperature Zwitterionic Ionic Liquids. French-Ukrainian Journal of Chemistry, 4(1), 85–94. https://doi.org/10.17721/fujcV4I1P85-9410.17721/fujcV4I1P85-94https://ir.library.knu.ua/handle/15071834/25574A novel series of zwitterionic ionic liquids based on (E) or (Z) isomer of an urocanic moiety containing a carboxylate group have been prepared. All synthesized compounds present melting points below 100°C. This value can be easily tuned by changing the length of alkyl chain grafted on the imidazolium moiety and the nature of isomer.  Hence, melting temperature as low as -20°C was obtained for Z isomer with a N1, N3-methyloctyl imidazolium moiety.enzwitterionic ionic liquidsurocanic acidimidazoliumСтаття
