“…In recent years, a nitrogen-rich CP as an energetic material has attracted extensive attention. − In the development of traditional energetic materials composed of C, H, O, and N, there is a contradiction between energy and sensitivity. The sensitivity of new materials often increases with the increase of energy, which makes their applications difficult due to safety problems. − …”

Eight kinds of energetic coordination polymers (ECPs) with multi-coordination were designed and synthesized by combining the carbonyl group with coordination potential in biuret with transition metal nitrates and perchlorates (Co2+, Ni2+, Cu2+, and Ag+). The structures of these complexes are confirmed by infrared spectroscopy, elemental analysis, and X-ray single-crystal diffraction. The physical and chemical performance test results show that the solvent-free ECPs 7 (Cu(BIU)2(ClO4)2) has the best performance (T dec = 328 °C, D = 7600 km·s–1, P = 27.8 Gpa, IS = 25 J, FS = 240 N). Among them, ECPs 7 and 8 (Ag(BIU)ClO4) have good detonation performance during hot plate and laser ignition tests (ECPs 7: P = 15 W, τ = 6 ms, E = 80 mJ; ECPs 8: P = 20 W, τ = 5 ms, E = 100 mJ). The result shows that improving the oxygen balance of ligands and constructing multidentate coordination structures may be a new effective strategy for improving the performance of laser-sensitive ECPs.

“…Energetic materials (EMs) attract extensive attention from the scientific community because of their wide range of applications as propellants, explosives, and pyrotechnics. 1–4 In the last few decades many interesting, energetic materials have been designed and subsequently synthesized including octanitrocubane (ONC), 5 2,4,6,8,10,12-hexanitrohexaaza-isowurtizitane (CL-20), 6 4,10-dinitro-2,6,8,12-tetra-oxa-4,10-diazatetracyclo[5.5.0.0 5,9 .0 3,11 ]-dodecane (TEX), 7 a formamidinium nitroformate (FANF), 7 b 1,3,5-trinitroperhydro-1,3,5-triazine (RDX), 8 dihydroxylammonium-5,5′-bistetrazolyl-1,1′-diolate (TKX-50), 9 and 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (HMX). 10 In addition to these well-known energetic compounds, a few aromatic energetic materials such as 2,4,6-trinitrobenzene-1,3,5-triamine (TATB), 11 2,4,6-trinitrotoluene (TNT), 11 picric acid (PA), 4 and 2,2′,4,4′,6,6′-hexanitrostilbene (HNS) 12 also attract the attention of materials chemists due to their high stability and good performance.…”

“…Generally, increasing the nitrogen content can effectively increase the energy level of compounds. − Therefore, in our previous work (seen in Figure ), we designed and synthesized several ligands and related complexes, including Cu(TZCA) 2 (ClO 4 ) 4 , Cu(AOCA) 2 (ClO 4 ) 2 , and Cu(PZCA) 2 (ClO 4 ) 2 (TZCA: 1 H -tetrazole-5-carbohydrazide, AOCA: 4-amino-1,2,5-oxadiazole-3-carbohydrazide, PZCA: 1 H -pyrazole-4-carbohydrazide). These ECCs have good explosive performance, but their mechanical sensitivity is high.…”

In order to further explore the effect of ligands on the performance of primary explosives and gain a deeper understanding of the coordination mechanism, we designed furan-2-carbohydrazide (FRCA), a ligand, by using oxygen-containing heterocycles and carbohydrazide. Then, FRCA and Cu(ClO4)2 were used to synthesize coordination compounds [Cu(FRCA)2(H2O)(ClO4)2]·CH3OH (ECCs-1·CH 3 OH) and Cu(FRCA)2(H2O)(ClO4)2 (ECCs-1). The structure of the ECCs-1 was confirmed by single-crystal X-ray diffraction, IR and EA characterization. Further experiments on ECCs-1 show that ECCs-1 has good thermal stability, but is sensitive to mechanical stimuli (impact sensitivity = IS = 8 J, friction sensitivity = FS = 20 N). The predicted value of the detonation parameter is D EXPLO 5 = 6.6 km s–1, P EXPLO 5 = 18.8 GPa, but the ignition test, laser test, and lead plate detonation experiment show that ECCs-1 has excellent detonation performance, which is very worthy of attention.
