Balancing high energy density with low sensitivity remains a key challenge in the development of advanced energetic materials. Here, we present an electronically self-regulation-driven hydrogen atom transfer strategy for the construction of fused heterocyclic energetic compounds. By integration of an alternating -NH2/-NO2/-NH2 motif into a 1,2,4triazolo4,3-bpyridazine scaffold, an in situ hydrogen atom transfer was triggered, enabling subsequent nitration of the amino group to generate a nitroimino functionality. Based on this strategy, compound 6 exhibits excellent detonation properties (D = 8896 m s-1 and P = 32.4 GPa) with low sensitivity and good molecular stability, demonstrating its promising application potential as an energetic material.
