摘要：

Cage-like octa(3-aminopropyl)silsesquioxane trifluoromethanesulfonate (OAP-POSS-CF3SO3) was prepared in higher yield (ca. 93%) with a shorter reaction time (ca. 5-6 h), when the hydrolytic condensation of 3-aminopropyltrimethoxysilane was performed using the superacid trifluoromethanesulfonic acid as a catalyst. The structure of the resulting OAP-POSS-CF3SO3 was confirmed mainly by Si-29 NMR, MALDI-TOF MS, ESI MS, and IR measurements. It is suggested that the lower pK(a) of the acid catalyst is an important factor leading to the improved yield for the preparation of OAP-POSS-CF3SO3.
