摘   要:
In this study, employing a simple anion exchange strategy and straightforward three-step synthetic route, a pair of promising nitrogen-rich heterocyclic cation and oxygen-rich anion were assembled together to generate two novel dinitramide energetic salts, both of which exhibit prominent detonation performance comparable to benchmark explosive RDX while possessing significantly lower mechanical sensitivity than RDX, thereby highlighting them as promising candidates for advanced secondary explosives. This work has directly led to a practical protocol for the design of chloride-free environmentally friendly IEMs, and accelerates the development of organic explosives with high-energy and low-sensitivity.
