Abstract High-performance energetic materials require good balance between energy and safety, which may be achieved through structural design. Herein, an energetic compound containing a furazan-triazole backbone linked by methylene bridges and a systematic series of corresponding energetic salts were synthesized, characterized structurally, and subjected to various performance tests. All the target compounds possessed good impact sensitivities (IS ​> ​24 ​J) and friction sensitivities (FS ​> ​240 ​N), as well as acceptable detonation velocities (D ​> ​7756 ​m ​s−1) and detonation pressures (p ​> ​23.6 ​GPa). In addition, the detonation performance of each salt was enhanced to some extent compared with that of the corresponding neutral compound. Moreover, a combination of theoretical calculations and the energetic performance parameters was used to elucidate the structure–property relationship of the target compounds. These findings will enrich future prospects for the design of insensitive energetic materials.

通过亚甲基桥将三唑和呋喃山骨架结合起来，用于新型不敏感的高能材料

摘要高性能含能材料要求在能量和安全性之间达到良好的平衡，这可以通过结构设计来实现。在此，合成了包含通过亚甲基桥连接的呋喃山三唑骨架的高能化合物和一系列系统的相应高能盐，对其结构进行了表征，并进行了各种性能测试。所有目标化合物都具有良好的冲击敏感性（IS> 24 J）和摩擦敏感性（FS> 240 N），以及可接受的爆轰速度（D> 7756 m s-1）和爆轰压力（p> 23.6 GPa）。此外，与相应的中性化合物相比，每种盐的爆炸性能都有一定程度的提高。此外，理论计算和高能性能参数的组合被用来阐明目标化合物的结构-性质关系。这些发现将丰富不敏感的高能材料设计的未来前景。
