Octasilsesquioxanes as Hybrid Nanocomposite Platforms. II. Synthesis, Characterization and Properties of Some Alkyl-functionalized Sislesquioxanes

The syntheses of octaalkylsilsesquioxanes 3, 4, 5 and 6 have been achieved by the platinum- catalyzed hydrosilylation of octahydrogensilsesquioxane 2 with _-halo-alkenes and other unsaturated substrates. These compounds were characterized by spectroscopic techniques and elemental analysis. Thermogravimetric analyses of 3 and 4 shows that they are reasonably stable thermally, and may act as building blocks to ceramics, nanometer ball bearing at around 400°C and photoresist materials.
