Abstract
Energetic metal–organic frameworks (EMOFs) are very promising as heat-resistant explosives, affording both thermal stability and energy properties. In this work, the self-assembly of high-energy nitrogen-rich linkers with nontoxic alkali-metal lithium/sodium leads to four new solvent-free EMOFs. Because of unparalleled decomposition temperature (Tdec = 403 °C) and heats of detonation (3.475 kcal·g–1), a 3D Li(I)-EMOF can be considered to be a superheat-resistant explosive candidate.
