      abstract     = {Ionic liquid crystals are ionic liquids that exhibit liquid
                      crystalline mesomorphism together with ionic conductivity.
                      As is known, confined liquid crystal mesophases can show
                      anomalous dynamics and phase behavior. Investigations
                      considering the factors controlling the macroscopic
                      properties of ILCs in confinement are rare in the
                      literature. This study reports the molecular mobility and
                      the phase transition behavior of a guanidinium-based
                      columnar ILC confined in the nanopores of self-ordered
                      anodic aluminum oxide membranes of various pore diameters
                      (25--180 nm) using broadband dielectric spectroscopy (BDS),
                      calorimetry, and X-ray scattering. It is aimed at revealing
                      in which way the pore size as well as the pore surface
                      wettability (hydrophobic or hydrophilic) alter the molecular
                      dynamics and phase transition behavior of this system. These
                      properties are crucial for applications. The DSC
                      investigations reveal the following: (i) the phase
                      transition temperature for the transition from the plastic
                      crystalline to the crystalline-liquid state has nonmonotonic
                      dependence versus the inverse pore diameter; and (ii) the
                      transition from the liquid crystalline to the isotropic
                      phase is suppressed for all nanoconfined samples. This
                      transition suppressed in the thermal signal was made evident
                      by BDS and X-ray scattering. It is discussed as a continuous
                      phase transition taking place in the pores instead of a
                      discontinuous first-order transition, as observed for the
                      bulk. BDS investigations show different relaxation processes
                      for bulk and nanoconfined ILC. The molecular origins of
                      various relaxation processes are discussed and suggested. It
                      is further shown that the self-assembly of this ILC is
                      dynamic in nature, which might apply for other ILCs too. The
                      obtained results will have implications for nanoscale
                      applications of ionic liquid crystals.},
