better oxygen balance than normally is found with their carbocyclic analogues, a higher percentage of their decomposition products will be N2. Pyrazole, triazole, tetrazole, tetrazine, furazan and furoxan derivatives are interesting high energy materials due to their highly positive heats of formation, high nitrogen content and good thermal stability deriving from their aromaticity. Recently, the combination
富含氮的杂环基化合物最常用于含能化合物,因为它们比碳环类似物具有更高的正形成热、密度和氧平衡。富氮化合物形成了一类独特的高能材料,其能量来源于其高形成热,直接归因于大量固有的高能 CN、NN、C=N 和 N=N 键。与通常的碳环类似物相比,更少量的氢和碳有助于更好的氧平衡,它们的分解产物中更高的百分比将是 N2。吡唑、三唑、四唑、四嗪、呋喃和呋喃衍生物由于它们的高形成热而成为有趣的高能材料,高氮含量和良好的热稳定性源于其芳香性。最近,偶氮基团与高氮杂芳环的结合得到了广泛的研究,因为偶氮键不仅使高氮化合物脱敏,而且显着增加了高氮化合物的形成热,例如 3,3'-偶氮双 (6-氨基-1,2,4,5-四嗪), 4,4'-偶氮二-1,2,4三唑, 1,1'-偶氮二(3-硝基-1,2,4,5-四唑), 1, 1'-azobis1,2,3-triazole, 4,4',6,6'-tetra(azido)azo-1
