Composite Energetic Materials Containing Nitrotriazalone Formed by Molecular Inclusion

The explosive properties of inclusion compounds containing the monoanion of the energetic compound 3-nitro-1,2,4-triazol-5-one (NTO^-) non-covalently bound to either of two larger, energetic, receptor complexes, namely 1-(2,4-dinitrophenyl)-1,4,7,10-tetraazacyclododecanezinc(II) or 1-(2,4-dinitrophenyl)-1,4,7,10-tetraazacyclododecanecopper(II), both as their monoperchlorate salts, are reported. The sensitivity of the receptor host-guest complexes to electrostatic discharge or friction was not found to differ from that displayed by the separate components. However, for thermal sensitivity it was found that whereas NTO^- desensitized the Zn(II) receptor complex it sensitized the Cu(II) receptor complex. For sensitivity to impact, measured using the Rotter impact test, it was found that NTO^- sensitized the Zn(II) receptor complex, but desensitized the Cu(II) receptor complex.
