Metal-Free Molecular Perovskite High-Energetic Materials

Crystal Growth & Design, Год журнала: 2020, Номер 20(3), С. 1891 - 1897

Metal-free energetic materials generally have the advantages of high gas yield and metal-free residue after combustion or explosion, enabling them to be widely used as explosives propellant components. As part a series our investigations on ABX3 molecular perovskite high-energetic materials, here we report five new members, (H2A)[NH4(ClO4)3], by using different organic cations H2A2+, i.e., 1-hydroxy-1,4-diazabicyclo[2.2.2]octane-1,4-diium for DAP-O4, piperazine-1,4-diium PAP-4, 1-methyl-piperazine-1,4-diium PAP-M4, homopiperazine-1,4-diium PAP-H4, 1-methyl-1,4-diazabicyclo-[2.2.2]octane-1,4-diium DAP-M4, respectively. Together with previously reported member, (H2dabco)[NH4(ClO4)3] (DAP-4, H2dabco2+ = 1,4-diazabicyclo[2.2.2]octane-1,4-diium), these six provide nice instances fine-tune oxygen balance, crystal density, thermal stability, detonation performance, changing A-site solely. The density functional theory (DFT) calculations Kamlet–Jacob (K–J) equation suggested that improving balance while keeping spherical shape match anionic cage in facilitates obtaining better providing an important clue designing advanced practicable materials. It is worth noting three compounds (PAP-4, DAP-O4) are expected exceed performances RDX both explosive propellant, which DAP-O4 has highest heat (6.21 kJ mol–1), velocity (8.900 km s–1), pressure (35.7 GPa), well higher specific impulse value (262 s).

Designing and synthesizing more advanced high-energetic materials for practical use via a simple synthetic route are two of the most important issues development energetic materials. Through an elaborate design rationally selected molecular components, new metal-free hexagonal perovskite compounds, which named as DAP-6 DAP-7 with general formula (H2dabco)B(ClO4)3 (H2dabco2+ = 1,4-diazabicyclo[2.2.2]octane-1,4-diium), were fabricated easily scaled-up using NH3OH+ NH2NH3+ B-site cations, respectively. Compared their NH4+ analog ((H2dabco)(NH4)(ClO4)3; DAP-4), has cubic structure, have higher crystal densities enthalpies formation, thus exhibiting calculated detonation performances. Specifically, ultrahigh thermal stability (decomposition temperatures (Td) 375.3 °C), high velocity (D 8.883 km·s−1), pressure (P 35.8 GPa); therefore, it exhibits potential heat-resistant explosive. Similarly, (Td 245.9 °C) excellent performance 9.123 km·s−1, P 38.1 GPa). Nevertheless, also possesses remarkably heat (Q 6.35 kJ·g−1) specific impulse (Isp 265.3 s), is superior to that hexanitrohexaazaisowurtzitane (CL-20; Q 6.23 kJ·g−1, Isp 264.8 s). Thus, can serve promising high-performance material use.
