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

Abstract

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 (T_d: 342.7–390.3 °C) and high detonation velocity (D: 8163–8337 m s⁻¹), demonstrating the effectiveness of the C–N coupling strategy for constructing novel heat-resistant energetic materials.
