| Abstract | Periodic mesoporous organosilica (PMO) are of growing interest because of numerous applications, especially in the field of separation and chromatography. This attraction is enhanced by the possibility of having a material owing a chemically selective surface, which is able to allocate chemical compounds in pure form. Nevertheless, the structural characterization of PMOs, especially regarding questions of porosity and pore accessibility cannot be answered by standard techniques, like gas adsorption. The combination of an adsorption experiment with in-situ smallangle X-ray scattering (SAXS) is a powerful experimental tool towards this direction. Due to contrast matching between the fluid and the matrix, the measured scattering patterns provide information about porosity and pore filling mechanisms of PMOs. |
