Fluorinatedpolyhedraloligomericsilsesquioxane (F-POSS) compounds were prepared by employing a facile, corner-capping methodology. Using this modular approach, fluorocarbons with varying degree of fluorine content and architecture were installed on the POSS cage of a partially condensed trisilanol. The melting properties of the F-POSS derivatives showed various influence by Si…F contacts via intermolecular
氟化多面体低聚倍半硅氧烷(F-POSS)化合物是通过采用简便的角封顶方法制备的。使用这种模块化方法,将具有不同氟含量和结构的碳氟化合物安装在部分冷凝的POSS笼上三硅烷醇。F-POSS衍生物的熔融特性显示出通过分子间堆积组装而受到Si…F接触的各种影响。所有F-POSS化合物的特征在于1 H,13 C,19 F和29 Si NMR光谱,X射线晶体学,热和元素燃烧分析。
