      abstract     = {Interfacial interactions significantly alter the
                      fundamental properties of water confined in mesoporous
                      structures with crucial implications for geological,
                      physicochemical, and biological processes. Herein, we
                      focused on the effect of changing the surface ionic charge
                      of nanopores with comparable pore sizes (3.5–3.8 nm) on
                      the dynamics of confined liquid water. The control of the
                      pore surface ionicity was achieved by using two periodic
                      mesoporous organosilicas (PMOs) containing either neutral or
                      charged forms of a chemically similar bridging unit. The
                      effect on the dynamics of water at the nanoscale was
                      investigated in the temperature range 245–300 K,
                      encompassing the glass transition by incoherent
                      quasi-elastic neutron scattering (QENS). For both types of
                      PMOs, the water dynamics revealed two distinct types of
                      molecular motions: rapid local movements and translational
                      jump diffusion. While the neutral PMO induces a moderate
                      confinement effect, we show that the charged PMO drastically
                      slows down water dynamics, reducing translational diffusion
                      by a factor of 4 and increasing the residence time by an
                      order of magnitude. Notably, by changing the pore filling
                      values, we demonstrate that for charged PMOs, this effect
                      extends beyond the interfacial layer of surface-bound water
                      molecules to encompass the entire pore volume. Thus, our
                      observation indicates a dramatic change in the long-range
                      character of the interaction of water confined in nanopores
                      with surface ionic charge compared to a simple change in
                      hydrophilicity. This is relevant for the understanding of a
                      broad variety of applications in (nano)technological
                      phenomena and processes such as nanofiltration and membrane
                      design.},
