文摘
- •
Vϕ of DMSO and DMF solutions of [Mor1,R][BF4] increase with increasing IL concentration at all investigated temperatures.
- •
Ion–ion interaction are stronger for DMF solutions than corresponding for DMSO.
- •
DMSO interacts more effectively with ionic liquids studied than DMF.
- •
Obtained results are the consequence of the cation size of the ionic liquid.
