Influence of solvent structural variations on the mechanism of facilitated ion transfer into room-temperature ionic liquids

The predominant mode of strontium ion transfer from acidic nitrate media into a series of 1- alkyl- 3- methylimidazolium- based room- temperature ionic liquids containing dicyclohexano- 18- crown- 6 ( DCH18C6) shifts from cation exchange to strontium nitrato- crown ether complex partitioning as the hydrophobicity of the ionic liquid cation is increased.
