Abstract
Energetic metal–organic frameworks (EMOFs), which combine energetic ligands with metal ions, hold promise as novel energetic materials to balance the sensitivity and safety of explosives. The coordinating solvent molecules have a significant effect on the energetic properties of EMOFs. Two EMOFs, [K(AFTO)·H2O]n (1) and solvent-free [K(AFTO)]n (2), were obtained at different reaction temperatures. EMOFs 1 and 2 exhibit excellent thermal stability (Td,1 = 569 K, Td,2 = 574 K), insensitivity to mechanical stimuli (FS ≥ 360 N, IS ≥ 40 J for 1; FS ≥ 360 N, IS = 35 J for 2) and satisfactory detonation performance (D1 = 8291 m s−1, P1 = 31.9 GPa; D2 = 8415 m s−1, P2 = 32.7 GPa) due to their different 3D framework structures and strong hydrogen bond networks.
