Strategies for molecular construction and performance regulation of heat-resistant energetic materials: An overview

With the rapid development of deep-well blasting, aerospace and other fields, heat-resistant energetic materials have attracted wide attention of scientists all over the world. In this paper, the latest research progress of heat-resistant energetic materials based on benzene ring, bridged nitrogen heterocyclic ring, coupled nitrogen heterocyclic ring, fused nitrogen heterocyclic ring, molecular perovskite and energetic metal-organic framework is reviewed. The review delves into the synthetic routes, physical and chemical properties of these diverse materials, facilitating a comparative analysis to deepen understanding of the correlation between molecular structure, detonation performance, and thermal stability. Such insights provide a framework for addressing the inherent trade-offs between these properties. Additionally, the paper highlights the pivotal research direction in heat-resistant energetic materials, emphasizing the significance of designing and synthesizing new bridged and nitrogen-fused ring heat-resistant compounds, as well as advancing molecular perovskite-based materials. These endeavors not only offer novel insight for future research but also serve as a guide for the design and synthesis of next-generation heat-resistant energetic materials.
