Silsesquioxanes Chemical Properties,Usage,Production

Synthesis

Silsesquioxanes are usually synthesized by hydrolysis of organotrichlorosilanes.An idealized synthesis is:8 RSiCl3 + 12 H2O → [RSiO3/2]8 + 24 HCl

Description

Silsesquioxanes are members of polyoctahedral silsesquioxanes ("POSS"), which have attracted attention as preceramic polymer precursors to ceramic materials and nanocomposites. Diverse substituents (R) can be attached to the Si centers. The molecules are unusual because they feature an inorganic silicate core and an organic exterior. The silica core confers rigidity and thermal stability.

Uses

A silsesquioxane is an organosilicon compound with the chemical formula [RSiO3/2]n (R = H, alkyl, aryl or alkoxyl).Silsesquioxanes are colorless solids that adopt cage-like or polymeric structures with Si-O-Si linkages and tetrahedral Si vertices.
