Facile synthesis of bicyclic heat-resistant energetic materials <i>via</i> a C–N coupling strategy

Heat-resistant energetic materials are critical for applications in extreme environments, such as aerospace vehicles and the exploitation of oil and gas resources. This study proposes an efficient C-N coupling strategy for facile construction of linked ring energetic materials with high thermal stability. Five new energetic materials (designated NPX-05 to NPX-09) exhibited outstanding thermal decomposition temperatures (<i>T</i>_d: 342.7-390.3 °C) and high detonation velocity (<i>D</i>: 8163-8337 m s^-1), demonstrating the effectiveness of the C-N coupling strategy for constructing novel heat-resistant energetic materials.
