通过氯硅烷和硅氮烷的组合，成功地实现了含氟离子的双四环笼型锗氧烷的八角硅烷化反应。三种不同的硅基--三甲基硅基、二甲基硅基和二甲基乙烯基硅基连接在锗氧烷笼子的角落上。用二甲基乙烯基硅基修饰的笼子的溶解度和反应活性显著提高，允许进一步反应。二甲基乙烯基硅化笼型有机硅氧烷与二甲基硅基笼型硅氧烷之间的硅氢化反应得到了多孔固体。用硅基对锗氧烷的角部进行官能化，应该可以在各种功能材料中提供有价值的构建块。
Eight corners of a double‐four ring cage‐type germanoxane, containing a fluoride ion, were successfully silylated by the combination of chlorosilanes and silazanes. Three different silyl groups, trimethylsilyl, dimethylsilyl, and dimethylvinylsilyl, were attached on the corners of germanoxane cage. The solubility and reactivity of the cage modified with dimethylvinylsilyl groups were significantly increased, allowing for further reaction. Hydrosilylation reaction between dimethylvinylsilylated cage geramanoxanes and dimethylsilylated cage siloxanes afforded porous solids. Functionalization of the corners of germanoxanes with silyl groups should provide valuable building blocks in various functional materials.
