The heat-resistant energetic compounds with thermal decomposition temperature higher than 300℃ reported in the past ten years from the aspects of molecular design,synthesis route and performance evaluation were briefly reviewed.From the perspective of molecular framework,these heat-resistant energetic molecules mainly include monocyclic,fused heterocy-clic,linked heterocyclic and ionic salts.Among them,the fused heterocyclic and linked heterocyclic are the basic characteris-tics and main directions of the current development of heat-resistant energetic materials.Based on the summary and analysis of the structure and properties of energetic molecules,the construction of large conjugation and hydrogen bonding systems is an effective strategy to improve the thermal stability of molecules.The rational design and layout of conjugated fused heterocyclic and linked heterocyclic skeleton,the introduction of hydrogen bonding system and the further expansion of conjugated structures are expected to realize the construction of ultra-high heat-resistant energetic molecules.
