Abstrakt

Small-angle X-ray scattering (SAXS) experiments were carried out to investigate systems consisting of silica nanoparticles bridged by imidazolium-based linkers. This characterization method delivers a quantitative description of the efficiency to order nanoparticles obtained from different chemical approaches. Two packing factors were extracted from the SAXS curves, where one characterizes the stacking of the ligands and the other the order of the nanoparticles. The amount of order can be controlled by using different ligands such as mono- and diimidazolium-based ones with different flexibilities or by varying the ligand length
