A Novel Method to Prepare Polysilsesquioxane Nanoparticles Possessing Bromoalkyl Groups

A novel method to prepare siloxane-based nanoparticles possessing bromoalkyl groups, which are reactive functional groups, by bromoalkoxylation and bromination of poly(vinylsil-sesquioxane) nanoparticles using N-bromosuccinimide and 1-butanol was developed. No shape distortion or fusion of nanoparticles after the chemical reaction was observed by transmission electron microscopy.
