Silica and hybrid silica hollow spheres from imidazolium-based templating agents

Résumé

Hollow or dense silica spheres were synthesized by the hydrolysis-condensation of tetraethoxysilane templated by an ionic liquid crystal. A hydrolysable silylated analog of these ionic liquid crystals was also submitted to a sol–gel reaction in a binary toluene–water mixture, yielding hybrid vesicles. All the materials were fully characterized by solid state NMR, FTIR, electron microscopies, N2 adsorption–desorption measurements, and their mechanism of formation was assessed thanks to in situ optical microscopy studies.
