摘要
The nitrate ester substitution derivatives of prismane were studied at the B3LYP/6-311G** level. The sublimation enthalpies and heats of formation in gas phase and solid state were calculated. The detonation performances were also predicted by using the famous Kamlet-Jacbos equation. Our calculated results show that introducing nitrate ester group into prismane is helpful to enhance its detonation properties. Stabilities were evaluated through the bond dissociation energies, bond order, characteristic heights(H50) and band gap calculations. The trigger bonds in the pyrolysis process of prismane derivatives were confirmed as O–ON_2 bond. The BDEs of all compounds were large, so these prismane derivatives have excellent stability consistent with the results of H50 and band gap.
