Abstract

Abstract: Octaphenylsilsesquioxane(OPhS) was prepared by a modifying method and a new core-shell nanocomposite, octa(2,4-dinitrophenyl)silsesquioxane, [(R₂PhSiO_1.5)₈, R=-NO₂, ODNPhS], was synthesized by nitration of OPhS in a mixed acid solution of nitric and sulfuric acids at about 60 ℃. Their molecular structures were determined by DRIFTS, ¹H NMR, ¹³C NMR spectra analysis. The thermal analysis shows that ODNPhS is an explosive that detonates at about 420 ℃.

Key words: Core-shell nanocomposite, Organic/inorganic hybrid, Octa(2,4-dinitrophenyl)silsquioxane, Thermal property
