English abstract:
A novel method was developed to synthesize 3-D networks built-on silica nanoparticles. Therefore functionalized silica nanoparticles bearing either a chloride or an imidazol end group were reacted via a nucleophilic substitution reaction. Furthermore the halide anions of the constructed ionic silica networks were exchanged to different anions. Various salts were investigated, KPF6, NaBF4 and LiTf2N. The anion metathesis was followed by means of X-ray powder diffraction (XRD) and changes in the structure of the network studied with small angle X-ray scattering (SAXS). This method allows tailoring of the physico-chemical properties of such new hybrid materials.
