Abstract:

The synthesis of Naphthyl8T8 POSS has been reproduced to enable a careful examination of its properties in comparison with Phenyl8T8, with the overall goal of ascertaining the influence of the peripheral architecture of symmetric aryl POSS compounds on macroscopic properties. A comparison of the characteristics of Phenyl8T8, and 1-Naphthyl8T8 possessing a geometrically larger periphery has revealed that the nature of the organic moieties affects POSS packing efficiency. The differences in packing efficiencies affect both the solvent solubility and thermal characteristics of these symmetric aryl POSS compounds.
