Abstract

In order to resolve the conflict between mechanical sensitivity and explosive performance, we utilized a retro-synthesis approach to design and synthesize the ligand 1H-imidazole-4-carbohydrazide (4-IMCA) and the complex Cu(4-IMCA)₂(ClO₄)₂ (ECC-1). The structure of the product was confirmed by single-crystal X-ray diffraction, IR and elemental analysis. The results showed that the physicochemical stability of ECC-1 was improved, including thermal stability (T_d = 200 °C), mechanical sensitivity (IS = 3 J, FS = 7 N), and explosive performance. Moreover, laser ignition (P = 22 W, τ = 3 ms, E = 66 mJ) and lead plate damage tests showed that the detonation ability of ECC-1 was not compromised.
