Abstract
Using quasielastic neutron scattering in the temperature range from 290 to 350 K, we
show that the diffusive motions in a room temperature ionic liquid [H2NC(dma)2][BETI] become
faster for a fraction of cations when the liquid is confined in a mesoporous carbon. This applies
to both the localized and long-range translational diffusive motions of the highly mobile cations,
although the former exhibit an unusual trend of slowing-down as the temperature is increased,
until the localized diffusivity is reduced to the bulk ionic liquid value at a temperature of 350 K.
