Abstract
Asymmetric aryl polyhedral oligomeric silsesquioxanes (ArPoss) compounds synthesized by the “corner-capping” of phenyl7Si7O9(OH)3 with aryl trichlorosilanes are described. The ArPoss compounds have the chemical structure:wherein Ph isphenyl and wherein R is selected from the group consisting of:and mixtures thereof.
