abstract = {The presence of oligoether functional groups in the cations
of ionic liquids has a significant effect on Li+
coordination. In this work, a series of
N-alkoxylether-N-methyl pyrrolidinium
bis(trifluoromethanesulfonyl)imide ionic liquids were
synthesized to investigate the effect of the number of ether
units on Li+ coordination and transport. The nature of Li+
coordination was elucidated through the combination of Raman
spectroscopy and heteronuclear Overhauser effect NMR
spectroscopy. The presence of a simple ether in the cation
side chain results in improved physical properties as
compared to N-alkyl-N-methyl pyrrolidinium-based ionic
liquids, but does not significantly affect Li+ coordination
possibly due to steric effects of the pyrrolidinium ring.
Increasing the number of ethylene oxide units in the side
chain results in the progressive displacement of IL anions
in the first Li+ solvation shell by IL cations due to the
preferential coordination of Li+ by the ether oxygen atoms.
The apparent transference number of the IL cation decreases
and that of the IL anion increases with increasing side
chain length. Unfortunately, this does not result in an
increase in the Li transference. Nonetheless, the results of
this study have important implications for electrolyte
systems where the desolvation of the metal cation from the
IL anions is the limiting factor in the charge transport
mechanism.},
