Construction of a Novel Nitrogen-Containing Cage-Like Scaffold, 9-Azatricyclo[4.2.1.0 ^3,7 ]octane, and the Synthesis of Two Energetic Derivatives

Organic cage-like frameworks can serve as crucial skeletal structures for the development of prospective energetic materials owing to their high inherent density, symmetry, and derivability. Herein, we show the construction of a novel nitrogen-containing cage-like framework, 9-azatricyclo[4.2.1.03,7]nonane-2,5-diol, from bicyclo[3.3.0]octane-2,6-diene. Thereafter, its two energetic derivatives were also prepared and characterized. The results of thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) show that the energetic derivatives possessed satisfactory thermal stability, and the calculation results (D = 8196 m·s–1 and 7343 m·s–1, P = 29.9 and 21.68 GPa) show good detonation performance, which implies that the 9-azatricyclo[4.2.1.03,7]nonane frameworks have the potential to be used for preparing new 3D energetic compounds with superior energy performance.
