Breaking the Density–Thermal Stability Trade-Off: Targeted Design and Construction of an Energetic Co-crystal

Achieving both high density and thermal stability remains challenging in energetic materials. This work presents a targeted co-crystal (DHANP·2HClO 4 ) prepared via molecular self-assembly. It exhibits a density of 2.03 g cm –3 and an onset decomposition temperature of 235 °C, demonstrating an excellent balance between these properties. Compared to conventional perchlorate-based materials, this co-crystal overcomes the typical performance trade-off, offering a promising strategy for designing advanced energetic materials with superior comprehensive performance.
