In this study, the synthesis, physicochemical properties and energetic performance of fused heterocycle based energetic materials with two or more rings are investigated. These compounds have been considered with a coplanar polycyclic structure, higher heats of formation (HOF) and ring-strain energy stored in the molecules. Good energetic performance, high thermal stability and low sensitivity toward destructive mechanical stimuli increase the safety of the synthesis, transfer, and storage of high- density energetic compounds. These properties make fused heterocyclic compounds a suitable alternative to conventional high-energetic materials for military and civilian applications Among the compounds studied, some of them have explosive performance comparable or higher than conventional explosives such as TNT, HMX, RDX or CL-20 and lower sensitivity to external stimuli. They are suitable candidate for replacement of conventional explosives. Because of their high specific impalse, some of them are suitable for use in high-performance propellant formulations. Also, the difference between melting point and decomposition temperature makes these fused heterocycles suitable as melt cast explosive.
