Synthesis of a Cage-like High Energy Density Compound with the 2-Azaadamantane Skeleton Containing Seven Nitro Groups at All-Bridge Positions.

The synthesis of azaadamantane-based energetic compounds with symmetrical structures and numerous explosophoric groups has always been a major challenge in the field of energetic materials. Herein, we report the synthesis of a fully bridged carbon-substituted 2-azaadamantane energetic compound with seven explosophoric groups. It exhibits a high crystal density (1.90 g cm-3) and excellent detonation properties (D = 8881 m·s-1, P = 37 GPa), which show that it has the potential to be applied as a high-energy density material.
