One of the key properties of explosives that makes them prone to detonation is a positive charge above the central regions of the molecular surface. Electrostatic potential maps were calculated for tetranitro-derivatives of benzene, naphthalene, anthracene, tetracene, and pentacene. Results of calculations performed at PBE/6-311G** level show that with the increase in the number of condensed aromatic rings positive values of electrostatic potentials in the central regions of studied nitroaromatic molecules decreases.[1] Results obtained by bond dissociation energy analysis are consistent with the calculated electrostatic potential maps indicating that aromatic system size could be used as a tool to modify the sensitivity toward detonation of nitroaromatic explosives. 1.
