Abstract:
An octacarboxy-silsesquioxane was designed and synthesised through a multiple-step regioselective reaction. This novel hybrid inorganic-organic compound presents highly attractive features for application as a building block, as it has a robust, rigid structure and a high number of carboxylic coordination sites organised in a cubic symmetry.
