摘要：

The structural characteristics, synthesis method, crystal characteristics and thermal decomposition performance of perchlorate based molecular perovskite energetic compounds (DAPs) were described. The research status in material modification and detonation performance were also summarized. The results show that DAPs are mainly synthesized based on the molecular assembly method, through a one-pot reaction from high performance oxidizer and low cost fuel. The perovskite energetic compounds (H2dabco)[M(ClO4)3](M = Na+,K+,Rb+,NH4+) correspond to DAP-1, DAP-2, DAP-3, DAP-4, respectively, and their crystal morphologies exhibit cube shape. The thermal decomposition peak temperature of DAPs are higher than 350℃, and the excellent thermal stability makes DAPs belonging to heat-resistant energetic materials. The addition of catalyst components can significantly change the thermal decomposition performance of DAP-4 ((H2dabco)[NH4(ClO4)3]). In terms of energy performance, the DAPs have comparable detonation performance with RDX. Finally, some proposal about the future direction of the research and development are put forward. It is pointed out that further studies about the DAPs represented by DAP-4 should be performed to understand the unique structure and properties of this material, and expand its application in the field of explosive.
