Ionic Liquids with Fluorine‐Containing Cations

Abstract

Interest in ionic liquids with fluorine-containing cations has grown markedly in recent years. The syntheses, characterization and properties of quaternary fluoroalkyl-substituted ammonium, imidazolium, triazolium, pyridinium, pyrazinium, pyridazinium, pyrimidinium, piperazinium, pyrrolidinium, oxazolidinium, and morpholinium salts have been studied in detail. By modifying the anion or the fluorine-containing substituent on the cation, a wide range of properties of fluorine-containing ionic liquids can be tuned, including

Stickstoffreiche energetische Salze und ionische Flüssigkeiten

“…Imidazoliumsalze Imidazoliumsalze mit fluorhaltigen Anionen spielen als ionische Flüssigkeiten eine führende Rolle. [74] In Verbindung mit Nitrat oder Perchlorat entstanden aus nitro-und azidosubstituierten Imidazolen jedoch auch die energetischen Feststoffe 97 a-h in hervorragenden Ausbeuten. [30] À , (101) wurde durch Umsetzung von Silberazid mit N,N,NTrimethylhydraziniumiodid erhalten.…”

Physico-Chemical Properties of Task-Specific Ionic Liquids

“…In another study was observed that the presence of fluorine in the structure of the IL (as cation or anion) provokes an increment of density. [71] Other halogens (e.g. iodine and bromide) increases significantly the density values [72] The presence of pentafluorosulfane (-SF 5 ) in the cation structure will lead to an increase of density and a reduced melting point.…”

Synthesis and Sorption Analysis of Task-specific Fluorous Ionic Liquids

“…Ionic liquids (ILs) with fluorine-containing cations [12,13] are known to facilitate the emulsification of fluoroalkanes when added to conventional ILs [14]. Solubilities of fluorinated gases in ILs with non-fluorous cations were also determined [15].…”
