Amino-containing oligosilsesquioxanes are synthesized by the hydrolytic polycondensation of 3‑aminopropyltriethoxysilane and its cocondensation with phenyltrimethoxysilane in ethanol. According to 1H and 29Si NMR spectroscopy, the oligomers contain incomplete cyclochain structures along with ladder fragments. It is suggested that the spontaneous gelation of the oligomers during long-term storage is due to the intermolecular interactions of siloxane chains with silanol and aminopropyl groups.
