Two powerful yet safe energetic materials (EMs) have been synthesized with high yield via a facile method. We used low-cost industrial products as starting materials and water as a solvent rather than organic solvents without generating harmful by-products during the two-step synthetic procedure. Purification of the target materials could be obtained through a simple separation process with low energy consumption. Moreover, the thermal stability, insensitivity, and explosive performance of these two EMs are better than that of commonly used energetic materials such as TNT and TATB (2,4,6-triamino-1,3,5-trinitrobenzene).
