In this study, a hypergolic linker (dicyanamide, DCA) and a highenergy nitrogen-rich ligand (1,5-diaminotetrazole, DAT) were applied to construct high-energy metal−organic frameworks (HEMOFs) with hypergolic property. Three novel metal−organic frameworks (MOFs) were synthesized via a mild method with fascinating 2D polymeric architectures, and they could ignite spontaneously upon contact with white fuming nitric acid (WFNA). The gravimetric energy densities of the three HEMOFs all exceeded 26.2 kJ•g −1 . The cupric MOF exhibits the highest gravimetric and volumetric energy density of 27.5 kJ•g −1 and 51.3 kJ•cm −3 , respectively. By adjusting the metal cations, high-energy ligands and hypergolic linkers can improve the performance of hypergolic MOFs. This work provides a strategy for manufacturing MOFs as potential high-energy hypergolic fuels.

High nitrogen content energetic compounds 3,6-diguanidino-1,2,4,5-tetrazine [(DGTz)(H2O)2] and its diperchlorate [(DGTz)(ClO4)2] were prepared and characterized by elemental analysis and Fourier transform infrared (FT-IR) spectroscopy. Their crystal structures were determined by applying X-ray single crystal diffraction. The hydrogen atoms in the 3- and 6-sites of the tetrazine heterocycle have been disubstituted by guanidine groups for (DGTz)(H2O)2, and two crystal water molecules were present. In the (DGTz)(ClO4)2 molecule, two ClO4 – and one DGTz2+ groups were bonded together by electrostatic attraction and hydrogen bonds. The thermal decomposition process of the two compounds was investigated through differential scanning calorimetry (DSC) and thermogravimetric/differential analysis (TG-DTG). The results of the decomposition are nearly gaseous products. The kinetic parameters of the exothermic process were calculated by using Kissinger's and Ozawa–Doyle's methods.

“…It is well known that high energy density is conducive to superior energy output. , The crystal density of these crystals varies in the range of 1.388–1.560 g cm –3 at 200 K, which is considerably higher than that of UDMH (0.79 g cm –3 ) and 1-butyl-3-methylimidazolium dicyanamide (BmimDCA) (1.06 g cm –3 ) . Furthermore, we calculated the energy densities of these HMOFs based on the Δ c H , including gravimetric energy density ( E g ) and volumetric energy density ( E v ).…”

Exploring novel hypergolic fuels for modern space propulsion is highly desired. However, the analysis and understanding of the structure and hypergolic performance at the molecular level are still insufficient. To understand the factors that dictate hypergolicity, we conducted a comparative study on a series of metal–organic frameworks (MOFs) characterized by the same topology but with varied ligand structures. The ignition delay (ID) time trend was found to be imidazole < triazole < tetrazole, and the rapid ID time was 8 ms. By combining experimental studies and density functional theory (DFT) calculations, we found that propargyl and cyanoborohydride groups that functioned as dual hypergolic triggers contributed to the hypergolicity, and a distinct electronic structure was detrimental to ID time. The structure–performance relationships presented herein can potentially provide some fundamental insights into the field of developing high-performance hypergolic fuels.
