Hyperbranched polyesters were found to be excellent materials for templating nanostructures in organosilicates. It was noted that their chain-end functionality and high solubility permits for the compatibilization of the polyester/methylsilsesquioxane (MSQQ) mixture on a nanoscopic scale. Hyperbranched polyesters can also be incorporated to the MSQQ matrix at higherloading levels, which in turn reduces the size of the pores of organosilicate films.
