Octaphenylsilsesquioxane(OPhS) was prepared by a modifying method and a new core-shell nanocomposite, octa(2,4-dinitrophenyl)silsesquioxane, [(R_2PhSiO_ 1.5)_8, R=—NO_2, 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 ℃.

Octophenylsilsesquioxane (OPhS) was prepared by a modifying method and a new core-shell nanocomposite, octa (2,4-dinitrophenyl) silsesquioxane, [(R_2PhSiO_1.5) _8, R = -NO_2, ODNPhS], was synthesized by nitration of OPhS in A mixed acid solution of nitric and sulfuric acids at about 60 ° C. 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 ° C.
