Kamlet-Taft Solvation Parameters of Solvate Ionic Liquids

The Kamlet-Taft solvent parameters of solvate ionic liquids (SILs) prepared from lithium salts with glyme and glycol ligands are determined. The dipolarity/polarisibilities (pi*) are high, similar to those found in conventional ionic liquids. The H-bond basicities (beta) depend strongly on the anion. The H-bond acidities (alpha) are high in both glyme and glycol SILs, indicating that the lithium is acting as a H-bond donor site. Poor SILs have glyme-rich and salt-rich regions. In these liquids the pi* and beta values are almost identical to the parent glyme or glycol, and the alpha values are determined by the salt alone.
