catalytic effect on the thermal decomposition of energetic materials. In this contribution, two high-energy CPs Cu2(DNBT)2(CH3OH)(H2O)3·3H2O (1) and [Cu3(DDT)2(H2O)2]n (2) (H2DNBT = 3,3′-dinitro-5,5′-bis(1H−1,2,4-triazole and H3DDT = 4,5-bis(1H-tetrazol-5-yl)-2H-1,2,3-triazole) were synthesized and structurally characterized. Furthermore, 1 was thermos-dehydrated to produce Cu2(DNBT)2(CH3OH)(H2O)3 (1a)
摘要 高能配位聚合物(CPs)不仅表现出良好的能量性能,而且对含能材料的热分解具有良好的催化作用。在这个贡献中,两个高能 CPs Cu2(DNBT)2(CH3OH)(H2O)3·3H2O (1) 和 [Cu3(DDT)2(H2O)2]n (2) (H2DNBT = 3,3′-合成了 dinitro-5,5'-bis(1H−1,2,4-triazole and H3DDT = 4,5-bis(1H-tetrazol-5-yl)-2H-1,2,3-triazole) 并在结构上进一步对1进行热脱水生成Cu2(DNBT)2(CH3OH)(H2O)3 (1a)。采用Kissinger法和Ozawa法研究了1、1a和2的热分解动力学。热分析和灵敏度测试表明,所有化合物都表现出较高的热稳定性和对外部刺激的低敏感性,同时所有化合物都具有较大的正生成焓,分别计算为 (1067.67 ± 2.62) kJ mol-1
