This review provides numerous studies on nitrogen-rich tetracyclic-based heterocyclic energetic materials including oxadiazole, tetrazole, triazole, pyrazole, imidazole and tetrazine. The article mainly describes the construction method of energetic skeleton, explosive modification, and properties of tetracyclic energetic materials. The structure-property relationship was obtained by comparing the properties of a series of nitrogen-rich energetic materials. Finally, authors summarize the synthesis laws of energetic skeletons, which provides reference for the development of energetic materials in the future. Many neutral nitrogen-rich heterocycles including oxadiazole, tetrazole, triazole, pyrazole, imidazole, triazine and tetrazine in the two or more ring systems with great performance have sprung up in the field of energetic materials recently. This review summarizes the design routes of nitrogen-rich polycyclic-based energetic materials especially for tetracyclic-based including the synthesis of energetic backbone, the construction of linkage and the introduction of energetic units. Also, the energetic performance of these polycyclic-based energetic materials and analyzes the structure-property relationship based on the combination of structure analysis, and performance comparison of all target compounds are provided. This work could make a positive impact of chemistry not only on HEDMs but also on other fields. [Display omitted]
