Abstract

Cage-like octa(trimethylsiloxy)silsesquioxane [ (Me3SiO)SiO1.5]8 has been synthesized via the trimethylsilylation of cubic tetramethylammonium silicate octamer [(Me4NO)-SiO1.5]8 with chlorotrimethylsilane. The silicate octamer can be selectively formed by the reaction of tetraethoxysilane Si(OEt)4 with aqueous tetramethylammonium hydroxide in equal molar ratio. Elementary analysis, FT-IR,1H,13C,29Si NMR are used to characterize these silsesquioxanes.
