Reaction of Co(II) with the nitrogen-rich ligand N,N-bis(1H-tetrazole-5-yl)-amine (H2bta) leads to a mixed-valence, 3D, porous, metal-organic framework (MOF)-based, energetic material with the nitrogen content of 51.78%, [Co9(bta)10(Hbta)2(H2O)10]n⋅(22 H2O)n (1). Compound 1 was thermohydrated to produce a new, stable, energetic material with the nitrogen content of 59.85% and heat of denotation of 4.537 kcal cm(-3), [Co9(bta)10(Hbta)2(H2O)10]n (2). Sensitivity tests show that 2 is more sensitivity to external stimuli than 1, reflecting guest-dependent energy and sensitivity of 3D, MOF-based, energetic materials. Less-sensitive 1 can be regarded as a more safe form for storage and transformation to sensitive 2.
钴(II)与富氮配体N,N-双(1H-四唑-5-基)-胺(H2bta)反应生成一种基于三维多孔金属有机骨架(MOF)的混合价态含能材料,氮含量为51.78%,即[Co9(bta)10(Hbta)2(H2O)10]n⋅(22 H2O)n(1)。化合物1经过热脱水处理后得到一种新的、稳定的含能材料,氮含量为59.85%,爆热为4.537 kcal cm(-3),即[Co9(bta)10(Hbta)2(H2O)10]n(2)。敏感性测试表明,化合物2对外部刺激的敏感性高于化合物1,这反映了基于三维MOF的含能材料的客体依赖性能量和敏感性。敏感性较低的化合物1可被视为一种更安全的储存形式,并可转化为敏感性较高的化合物2。
