Energetic substances with layered crystal packing have been identified as the most promising next-generation high-energy materials (HEMs) due to their excellent insensitivity. The challenge, however, is how design HEMs. In this study, a novel strategy called "acceptor–donor separation" was proposed control layer-by-layer stacking of energetic molecules through directional hydrogen boding: that is, bond donor and acceptor are located in different segments at least one them has conjugated planar structure, which will enable fragments be infinitely extended two-dimensional plane form target structure. experimental results showed three exemplary designed by using possess expected structures, confirmed single-crystal X-ray diffraction, demonstrating robustness strategy. Moreover, as-synthesized HEMs all exhibit insensitivity (impact sensitivity IS > 40 J; friction FS 360 N), affording safety far beyond those powerful use today. Especially, hydroxylammonium salts good detonation performance (detonation velocity D = 8924 m s–1; pressure P 36.9 GPa) comparable 1,3,5-trinitro-1,3,5-triazine (RDX), high explosives

Reaching the goal of developing an insensitive high-energy molecule (IHEM) is a major challenge. In this study, 3,5-diamino-6-hydroxy-2-oxide-4-nitropyrimidone (IHEM-1) was synthesized in one step from 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide hydrate (ICM-102 hydrate). The density compound IHEM-1 1.95 g cm–3 with decomposition temperature 271 °C. Its detonation velocity and pressure are 8660 m s–1 33.64 GPa, respectively, which far superior to performance 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), while its sensitivity identical that TATB. addition, four derivatives (1a, chloride; 1b, nitrate; 1c, perchlorate; 1d, dinitramide) were prepared on basis weak base site (N–O group) show excellent energetic properties. By combining series advantages, including simple preparation, high yield, density, very low solubility aqueous solution, thermostability, insensitivity, performance, approaches ideal molecule. Compounds 1b–1d also competitive as new high-energy-density materials.

Abstract Owing to its simple preparation and high oxygen content, nitroformate [ − C(NO 2 ) 3 , NF] is an extremely attractive oxidant component for propellants explosives. However, the poor thermostability of NF-based derivatives has been unconquerable barrier more than 150 years, thus hindering application. In this study, first example a nitrogen-rich hydrogen-bonded organic framework (HOF-NF) designed constructed through self-assembly in energetic materials, which NF anions are trapped pores resulting via dual force ionic hydrogen bonds from strengthened framework. These factors lead decomposition temperature HOF-NF moiety being 200 °C, exceeds challenge thermal stability over 180 °C time among compounds. A large number compounds with stabilities excellent properties can be synthesized on basis work.

Structure–performance investigation has become one of those significant trends for energetic materials and crystallography inevitably. Herein, we report two new deriving from a famous thermally stable explosive benzopyridotetraazapentalene, which was first developed by Huynh Hiskey, et al., at Los Alamos National Laboratory.

Understanding their structures, properties, performances, relationship among them is basis rational design materials. Moreover, conjugated systems, density overlap regions indicator analysis also employed necessarily visualizing quantifying covalent noncovalent interactions. It evident that this strategy incorporating groups into increased coplanarity fused ring, owing contribution hydrogen bonding π–π interactions, can further decrease sensitivity. However, found integrity intramolecular -bonding interaction critical factor, affected thermal stability molecules with inserting progressively. notable diamino-substituted compound 8 exhibits comparable (320 °C) HNS, more dense (d: 1.84 g cm–3), higher nitrogen content (37.43%), lower sensitivity (impact sensitivity: 12 J, friction > 360 N), superior HNS. These discoveries effectively assist preparation other promising toward future high-performing energy applications.
