A silsesquioxane is an organosilicon compound with the chemical formula [RSiO3/2]n (R = H, alkyl, aryl, alkenyl or alkoxyl.). Silsesquioxanes are colorless solids that adopt cage-like or polymeric structures with Si-O-Si linkages and tetrahedral Si vertices. Silsesquioxanes are members of … See more Silsesquioxanes are known in molecular form with 6, 8, 10, and 12 Si vertices, as well as polymers. The cages are sometimes labeled T6 T8, T10, and T12, respectively (T = tetrahedral vertex). The T8 cages, the most … See more Cage-Rearrangement Reorganization of the siloxane cage-like core (T8 → T10) can be performed, including isolation of intermediates, and cage rearrangement … See more A well studied example of a partially condensed silsesquioxanes is the trisilanol Cy7Si7O9(OH)3, prepared by the slow (months) hydrolysis of trichlorocyclohexylsilane (C6H11SiCl3). The same cage can be prepared by acid-mediated cleavage … See more Silsesquioxanes are usually synthesized by hydrolysis of organotrichlorosilanes. An idealized synthesis is: 8 RSiCl3 + 12 H2O → [RSiO3/2]8 + 24 HCl The formation of HCl negatively impacts the relative rates of hydrolysis and condensation of … See more Electronic materials Films of organosilsesquioxane, e.g., poly(methylsilsesquioxane), have been examined for semiconducting devices.
