Abstract

The geometries of ten benzenoid energetic materials are fully optimized by employing B3LYP and B3P86 methods with the 6–31G** basis set. Bond dissociation energies (BDEs) for the removal of the NO2 group in benzenoid molecules are calculated at the same level. The calculation results show that the insertion of an electron withdrawing group increases the stability of the molecules, while the insertion of an electron donating group reduces the stability of the molecules. In addition, the relationship between the impact sensitivities and the weakest BDE values is examined. There exists a good linear correlation between the impact sensitivity and the ratio of the BDE value to the molecular total energy.
