Hypergolic Triggers as Cocrystal Formers: Cocrystallization for Creating New Hypergolic Materials with Tunable Energy Content

preprint

We demonstrate a cocrystal-based strategy to create new solid hypergols, i.e. materials exhibiting spontaneous ignition in contact with an oxidant, in which the energy content and density of the material can be changed without affecting the ignition delay. Using an imidazole-substituted decaborane as a hypergolic "trigger" component, in combination with energy-rich but non-hypergolic nitrobenzene, provides a hypergolic cocrystal with an ultrashort ignition delay, composed of hypergolic and fuel-containing domains.
