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 phenyl7Si7O9OH3, cage symmetry is disrupted, which significantly increases solubility over phenyl8Si8O12. Thermal characteristics are retained, which makes these materials suitable for use in high performance polymers. Reasonable yields 29- 95 were obtained for the reactions.
