The Coplanar Family of Bis(nitrotriazoles) Tetrazine and Oxides Based as
Energetic Compounds
Abstract
Abstract: Searching for energetic materials with balanced detonation
performance and sensitivity is the enduring ambition in the evolution of
high energy density materials (HEDMs). The coplanar molecular structure
of energetic compound has a powerful impact on performance. Herein, the
novel compounds of bis(nitrotriazoles) tetrazine (BNTT) was designed and
investigated by density functional theory(DFT) method. However, the
coplanar BNTT’s oxides would a highlight of molecular design with good
balance between superior performance with acceptable sensitivities.
Results show that all these designed compounds possess high densities,
positive heats of formation, remarkable detonation performance, and
acceptable impact sensitivity. In particular, B1-3 possess higher
density (ρ=1.97g·cm-3) and exhibits the better balance between
detonation performance (Q=1779.83 cal·g-1, D=9.48km·s-1, P=42.01GPa) and
sensitivity (h50%=28cm) than RDX. The theoretical study offer that all
novel compounds possess acceptable sensitivity. It may be seen as the
potential candidates of HEDMs.
