Host–guest energetic materials constructed by incorporating oxidizing gas molecules into an organic lattice cavity toward achieving highly-energetic and low-sensitivity performance

Abstract

A promising strategy for the preparation of novel gas inclusion host–guest energetic materials was provided by incorporating powerful oxidizer N₂O into the crystal lattice cavity of 2,4,6,8,10,12-hexanitrohexaazatetracyclododecane (HNIW). The HNIW/N₂O complex crystal exhibits a surprisingly high crystallographic density (2.038 g cm⁻³ at 298 K), more thermal stability, better predicted detonation properties and lower sensitivity compared to ε-HNIW due to its enhanced packing density, improved oxidation effect and added heat-release after N₂O insertion.
