abstract = {The structure and dynamics of the ionic liquid
1-ethyl-3-methylimidazolium acetate (EMIMAc) in porous glass
with pores of the size 40 and 100 Å is determined in
comparison to the bulk liquid. We employed x-ray diffraction
to measure the domain structure, and neutron backscattering
for the dynamics. In confinement, the liquid displays
onion-like domain structuring while in bulk the liquid is
largely forming a bicontinuous structure similar to
microemulsions. This also has an effect on the dynamics of
the liquid at high temperatures (373K): The ions in the bulk
can diffuse along the domain boundaries while they need to
cross the domains in the ordered state in confinement. At
low temperatures, the attractive forces of all ions are such
strong – we have a highly viscous fluid – such that the
diffusion in any direction is similarly slow, and the exact
domain structure plays a minor role.},
