Due to the superior thermal stability， good modification and appropriate ring tension of imidazole based energetic compounds， they were considered as an important research direction of high energy materials. This review summaries recent progresses of synthesis， property and application of energetic imidazole-bridged azoles， such as bisimidazoles， triazolyl imidazoles and tetrazolyl imidazoles and their energetic salt derivatives. It was found that single or double bond linked bisimidazoles had better thermal stabilities and mechanical sensitivities， higher densities and donation properties than their mono-cyclic imidazole analogs， and could realize the balance between energy and safety which is difficult to be realized by introducing nitrogen-rich energetic groups， connecting groups and formation of energetic salts into mono imidazolyl rings. On the other hand， bicyclic azoles with two different nitrogen heterocyclic structures linked by C─C bond or C─N bond usually has the advantages of combing the good properties of their related structure characteristics， making it an important direction for development of novel high nitrogen and high energy compounds in the future. This review summarizes the recent advances in energetic imidazole-bridged azoles and proposes an efficient construction strategy for designing high nitrogen content， high energy and good safety based on triazolyl imidazole and tetrazolyl imidazole building blocks.
