Thermodynamic Stability and Kinetic Lability of Fully-Condensed Fluorinated Polyhedral Oligomeric Silsesquioxane (POSS) Cages (Preprint)

Abstract

Polyhedral Oligomeric Silsesquioxane (POSS) cages [RSiO(sub 1.5)]n are a class of nano-particles that are being exploited as property modifiers to virtually every type of polymer imaginable. The most common of these materials are the R8Si8O12 derivatives (also known as the T(sub 8's)), as the octomeric cage is preferentially formed in almost all synthetic pathways reported. However, well-defined oligomeric cages with n = 6, 10, 12 or 14 are also known and their polyhedral structures proven with single crystal X-ray crystallography.
