      abstract     = {The temperature dependence of the structure of water
                      confined in hydrophilic mesostructured porous silica
                      (MCM-41) and hydrophobic benzene-bridged periodic mesoporous
                      organosilicas (PMOs) is studied by Raman vibrational
                      spectroscopy. For capillary filled pores $(75\%$ relative
                      humidity, RH), the OH stretching region is dominated by the
                      contribution from liquid water situated in the core part of
                      the pore. It adopts a bulklike structure that is modestly
                      disrupted by confinement and surface hydrophobicity. For
                      partially filled pores $(33\%$ RH), the structure of the
                      nonfreezable adsorbed film radically differs from that found
                      in capillary filled pores. A first remarkable feature is the
                      absence of the Raman spectral fingerprint of low-density
                      amorphous ice, even at a low temperature (−120 °C).
                      Second, additional bands reveal water hydroxyl groups
                      pointing toward the different water/solid and water/vapor
                      interfaces. For MCM-41, they correspond to water molecules
                      acting as weak H-bond donors with silica and dangling
                      hydroxyl groups oriented toward the empty center of the
                      pore. For benzene-bridged PMO, we found an additional type
                      of dangling hydroxyl groups, which we attribute to water at
                      the hydrophobic solid interface.},
