abstract = {The effect of pore wall chemistry and pore diameter on the
structure of confined water was studied by X-ray scattering
on water confined in periodic mesoporous organosilicas
(PMOs). A shift in the first structure factor peak at q
$≈$ 1.8 Å$^{−1}$ reveals a variation in the density of
the confined water in dependence of hydrophilicity and pore
size. Smaller and more hydrophilic pores induce a lower
density in the water. In contrast to bulk water, the pair
distribution functions (PDFs) of confined water show a
splitting of the second-neighbour peak into either two, in
the case of smaller and more hydrophilic pores, or three
separate peaks, in larger and more hydrophobic pores. From
the running coordination number we conclude that smaller and
more hydrophilic confinement leads to a stronger developed
tetrahedral network in confined water, while confinement in
larger and hydrophobic pores give tetrahedral arrangements
that are bulk-like or even less pronounced than in bulk
water.},
