Title

INFLUENCE OF WATER ON THE DYNAMICS OF A PROTIC IONIC LIQUID

Abstract

We propose to investigate the dynamics in a new class of electrolytes know as water-in-protic ionic liquids (water-in-PILs). In these systems a nano-segregated structure (length scale 1-10 nm) is formed where aqueous domains coexist with apolar and polar domains of the ionic liquid. On the macroscopic level an increase in transport properties is found and is proposed to be linked to local ion-ion interaction. The aim of this experiment is to address the influence of water on the local cation ion dynamics and its link to the macroscopic dynamics. With the WASP instrument we directly access the relevant time and length scales (ps-ns and Å-nm) and with selective deuteration we can directly focus on the cation dynamics.
