Abstract
A number of dicationic ionic liquids with a disiloxane linker between imidazolium cations and bis(trifluoromethylsulfonyl)imide anion were synthesized and characterized. Melting points, viscosity, and volatility in a vacuum were measured; the thermal and hydrolytic stability of ionic liquids were also studied. The dependence of the properties on the structure of substituents in the cation of the ionic liquid was demonstrated.
Highlights
Ionic liquids (ILs), due to their specific properties–high polarity and low saturated vapor pressure, are widely used in various fields of science and technology
This paper presents the results of a study of the influence of substituents in the imidazolium cation and the structure of the linker between cations on the properties of dicationic ILs with bis(trifluoromethylsulfonyl)imide anion: melting point, viscosity, volatility, thermal, and hydrolytic
The present study of the properties of a number of bis(trifluoromethylsulfonyl)imide disiloxanebased dicationic ILs with different linker structures and the nature of substituents in the cation shows that the nature of the substituents in the imidazolium cation significantly affected the properties of
Summary
Ionic liquids (ILs), due to their specific properties–high polarity and low saturated vapor pressure (volatility), are widely used in various fields of science and technology. As polar solvents, they are used in organic synthesis [1,2], synthesis of metal and metal oxide nanoparticles [3,4] and metal-organic frameworks (MOF) [5,6]. High thermal stability combined with high polarity determines their use as electrolyte components in lithium batteries and solar cells [7,8]. Low saturated vapor pressure allows the use of ionic liquids as benign solvents for green chemistry [9]. A special feature of ionic liquids is the possibility of using them as a working fluid under dynamic vacuum conditions [15,16,17]
