A simple way of transforming a colloidal dispersion of nanoparticles into a mesoporous solid with noticeable thermal stability is described. The strategy consists into the partial replacement of the shell of monotopic capping ligands, with proper functionalization to impart good dispersability, by rigid polytopic ligands that favor a controlled aggregation.
