以3-氨基丙基七异丁基倍半硅氧烷(POSS)为原料，通过选择性开角反应和封角反应，成功地合成了对取代的双(3-氨丙基)六异丁基-多面体倍半硅氧烷(POSS)。用密度泛函理论方法研究了开角反应的选择性。POSS单体与均苯四甲酸二酸酐聚合得到黄色的、独立的薄膜。
A para-substituted bis(3-aminopropyl)hexaisobutyl-polyhedral oligomeric silsesquioxane (POSS) was successfully synthesized via a selective corner-opening reaction of 3-aminopropylheptaisobutyl-POSS and a subsequent corner-capping reaction. The selectivity of the corner-opening reaction was studied by density functional theory calculations. Polymerization of the POSS monomer with pyromellitic dianhydride resulted in a yellow, self-standing film.
