      abstract     = {The intrinsic ionic nature of room temperature ionic
                      liquids (RTILs) bears the potential to replace classical
                      aqueous electrolytes in electrochemical applications, for
                      example in metal–air batteries. For a systematic
                      adjustment of RTIL properties in porous cathodes, the ionic
                      arrangement under confinement is of prime importance. Using
                      spectrally resolved pulsed gradient stimulated echo nuclear
                      magnetic resonance (PGSTE-NMR) and spin–lattice NMR
                      relaxation time (T1) distributions, the dynamics of
                      1-methyl-1-propylpyrrolidiniumbis(trifluoromethylsulfonyl)imide
                      ([Pyr13][Tf2N]) confined to carbon black were investigated.
                      A considerable dependence of the [PYR13] mobility on the
                      loading fraction of the carbon black pore space was found.
                      There is evidence for a preferential layering of the RTIL
                      adjacent to the carbon surface and a dependence of the ionic
                      configuration on the local structure of the carbon surface.
                      The inversion efficiency of inversion-recovery T1 data
                      indicates a quasi-stationary layer at the carbon surface
                      with solid-like properties, where the bulk-like properties
                      of the RTIL are adopted as the distance to the surface
                      increases. From the NMR diffusion data an intermediate layer
                      between the quasi-stationary and the bulk-like RTIL is
                      evident. This layer shows a particularly strong pore space
                      loading dependence. While it has an anisotropic,
                      two-dimensional mobility with reduced diffusion
                      perpendicular to the surface at any loading, when it
                      interfaces a gas phase at low loading its mobility is higher
                      than bulk diffusion by up to an order of magnitude and
                      chemical exchange with other layers is low. This layer
                      appears to be of particular importance for the ion exchange
                      between RTIL environments with different spacing from the
                      carbon surface and hence crucial for the overall dynamics of
                      RTILs in the investigated porous environment.},
