obtaining a better detonation performance, providing an important clue for designing advanced practicable high-energetic materials. It is worth noting that three compounds (PAP-4, PAP-H4, and DAP-O4) are expected to exceed the performances of RDX as both explosive and propellant, in which DAP-O4 has the highest detonation heat (6.21 kJ mol–1), detonation velocity (8.900 km s–1), and detonation pressure (35
不含金属的高能材料通常具有高产气量和燃烧或爆炸后不含金属的残留物的优点,使其能够广泛用作炸药和推进剂组分。作为我们对ABX 3分子钙钛矿高能材料的一系列研究的一部分,在此我们通过使用不同的有机阳离子H 2报告五个新的无金属成员(H 2 A)[NH 4(ClO 4)3 ]。一个2+,即DAP-O4的1-羟基-1,4-二氮杂双环[2.2.2]辛烷-1,4-二鎓,PAP-4的哌嗪-1,4-二鎓,1-甲基-哌嗪-1,4对于PAP-M4,分别为-diium,PAP-H4为homopiperazine-1,4-diium,对于DAP-M4为1-methyl-1,4-diazabicyclo- [2.2.2] octane-1,4-diium。与先前报道的成员(H 2 dabco)[NH 4(ClO 4)3 ](DAP-4,H 2 dabco 2+= 1,4-二氮杂双环[2.2.2]辛烷-1,4-二甲基
