Increasing the Solubility of Inert Peripherally Aromatic POSS

Abstract

New POSS compounds with high temperature capability and good solubility in various organic solvents have been developed. By placing a single polycyclic aromatic group (naphthyl, phenanthryl, or pyrenyl) on a corner (via a "corner-capping" reaction) of (phenyl)7Si7O9(OH)3, cage symmetry is disrupted, which significantly increases solubility over (phenyl)8Si8O12. Thermal characteristics are retained, which makes these materials suitable for use in high performance polymers. Reasonable yields (29- 95%) were obtained for the reactions.
