As an emerging high-energy substance， the development of perovskite energetic materials in both variety and quantity has more urgency. The first perchlorate-based double perovskite energetic material ｛（C₆H₁₄N₂）₂［Na（NH₄）（ClO₄）₆］｝_n （DPE-1） and a single perovskite energetic material ［（C₄H₁₂N₂）K（ClO₄）₃］_n （PAP-2） were synthesized by a solution-based method. The chemical structure， thermal stability， detonation performance， and mechanical sensitivity of both DPE-1 and PAP-2 were systematically investigated. Single-crystal X-ray diffraction analysis shows that DPE-1 crystallizes in a double perovskite structure with space group Pa-3， while PAP-2 crystallizes in a single perovskite structure with space group Pnma. Compared with the previously reported periodate-based double perovskite energetic material （C₆H₁₄N₂）₂［Na（NH₄）（IO₄）₆］｝_n（DPPE-1）， DPE-1 exhibits significant improvements in the thermal decomposition temperature （T_dec=368.9 ℃）， detonation velocity （D=8858 m·s^-1）， detonation pressure （p=38.4 GPa）， impact sensitivity （IS >40 J）， and friction sensitivity （FS=20 N）. These results validate the feasibility of exploring high-performance， green primary explosives within the double perovskite structural framework. PAP-2 demonstrates comparable thermal stability （T_dec>280 ℃） and detonation performance （D >8500 m·s^-1， p >30 GPa） with other single perovskite energetic materials in the same series， but its impact sensitivity is significantly increased and friction sensitivity is significantly reduced.
