Silsesquioxane - Wikipedia
A silsesquioxane is an organosilicon compound with the chemical formula [RSiO 3/2] n (R = H, alkyl, aryl, alkenyl or alkoxyl.). [1] Silsesquioxanes are colorless solids that adopt cage-like or polymeric structures with Si-O-Si linkages and tetrahedral Si vertices.
Silsesquioxane - an overview | ScienceDirect Topics
A silsesquioxane is a chemical formula complex [RSiO 3/2] n (R=H, alkyl, aryl or alkoxyl). Silsesquioxans are representatives of polyoctahedral silsesquioxane (POSS), which, as precursors to ceramic materials and nanocomposites, have drawn interest.
