Preparation of Polyhedral Oligomeric Silsesquioxanes Containing Carboxyl Side-Chain Groups and Isolation of a Cage-Like Octamer Using Clay Mineral

The hydrolytic condensation of 3-(triethoxysilyl)propyl succinic anhydride (TESPSA) in water using bulky base or acid catalysts such as tetra-n-butylammonium hydroxide (n-Bu4NOH) or trifluoromethanesulfonic acid, respectively, afforded mixtures containing polyhedral oligomeric silsesquioxanes (POSSs...
