We present a quasi-elastic neutron backscattering study of the ionic liquid 1-N-butylpyridinium bis- ((trifluoromethyl)sulfonyl)imide [BuPy] [Tf2N] confined in carbide-derived nanoporous carbon samples of different pore sizes. Elastic and inelastic fixed window scans while varying the temperature between 2 K and 350 K as well as quasi-elastic spectra acquired at selected temperatures allow us to infer the thermally-activated molecular mobility of the spatially nanoconfined ions.
