order to meet the high demands of modern energetic materials, numerous routes have been explored by the researchers. In this study, a ring replacement strategy was designed to enhance the energetic properties. The ring replacement compounds 11 (N,N′-methylenebis (N-(4-(2H-tetrazol-5-yl)-1,2,5-oxadiazol-3-yl)- nitramide) and 15 (N,N′-ethylenebis (N-(4-(2H-tetrazol-5-yl)-1,2,5-oxadiazol-3-yl)- nitramide)
摘要 为了满足现代含能材料的高要求,研究人员探索了多种途径。在这项研究中,设计了一种环置换策略来增强能量特性。环置换化合物 11 (N,N'-亚甲基双 (N-(4-(2H-tetrazol-5-yl)-1,2,5-oxadiazol-3-yl)-nitamide) 和 15 (N,N' -亚乙基双 (N-(4-(2H-tetrazol-5-yl)-1,2,5-oxadiazol-3-yl)-nitamide),其中连接到呋咱主链的恶二唑环被四唑环取代是经X射线单晶衍射和核磁共振(1H、13C、15N)表征,结果化合物表明置换化合物的生成热和爆轰性能明显优于前驱体化合物,化合物的氮含量11 和 15 分别从 41.18% 和 39 提高。分别为81%~54.9%和53.08%,属于高氮化合物范畴。总之,这项工作中的环置换策略为改善含能材料的性能提供了新的途径。
