Abstract: Ammonium-functionalized polyhedral oligomeric silsesquioxanes (POSSs) with only cage-like octamers were selectively prepared in high yields (ca. 90%) within relatively short reaction time (7–12 h), when the hydrolytic condensations of 3-aminopropyltrimethoxysilane (APTMS), 3-(2-aminoethylamino)propyltrimethoxysilane (AEAPTMS), and an… read more here.
