Starting from potassium cinnamate, photoreactive mono‐, octa‐, and deca(propyl cinnamate)‐functionalized cage silsesquioxanes were synthesized by simple nucleophilic substitution reactions with chloropropyl‐substituted octasilsesquioxanes. Among them, octa(propyl cinnamate)silsesquioxane exhibited some remarkable behavior, including high photopolymerization conversion of double bonds under UV irradiation and thermal stability. These compounds can act as pure photoreactive nanobuilding blocks for the preparation of hybrid nanocomposites with specific properties.
