Branched and Cyclic Alkyl Groups in Imidazolium - Based Ionic Liquids: Molecular Organization and Physico - chemical Properties

Popis výsledku v původním jazyce

In the present work, three imidazolium bis{(trifluoromethyl)sulfonyl}imide ionic liquids with a linear alkyl chain (1-pentyl-3-butylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [C(4)C(5)Im][Tf2N]), with branching (1-isopentyl-3-butylimidazolium bis{(trifluoromethyl)sulfonyl}imide [C(4)iC(5)Im][Tf2N]), or with a cyclic group (1-cyclopentyl-3-butylimidazolium bis{(trifluoromethyl)sulfonyl}imide, [C(4)cC(5)Im][Tf2N]) were synthesized for the first time. Such variation in structure could be of interestto possible applications of the present ionic liquids as task-specific ionic liquids. To understand the influence of the structure on their macroscopic properties, their density and two transport properties (viscosity and electrical conductivity), were measured as function of temperature. The introduction of branching has no effect on the density values whereas these show an increase when a cycle is substituted to the cation. Both branching of the alkyl chain and the presence of the cycl
