The B3LYP/6-31G calculations on the four complexes show that the largest interaction energy is-13.98 kJmol^(-1) in the complex composed of HMX and hexaazacalix [3]-p-triarene [3]-2-amido-1, 3, 5-triazine. Results show that intermolecular interaction energies of azacalix [6] arenes with substituted groups are stronger than that without substituted groups, and intermolecular interaction energies of azacalix [6] arenes with amido groups are stronger than that with nitryl groups.
