在水热和酸性条件下合成了一种新的无溶剂含能MOF[Pb(HBTI)]n(1)(H3BTI=4，5-双(1H-四氮唑)-1H-咪唑)。采用元素分析、红外光谱、热重分析、差示扫描量热仪(DSC)和扫描电子显微镜对其进行了表征。单晶X-射线衍射分析表明，1具有刚性的三维骨架结构，无溶剂分子。热分析表明，1的热稳定性可达325 °C。用基辛格和小泽法测定了1的放热分解过程的非等温动力学参数和表观热力学参数。通过氧弹燃烧量热法测定了1的标准摩尔生成热。计算了1的爆轰性能(爆热、爆速和爆压)，并进行了感度试验。此外，用差示扫描量热法考察了1作为助燃剂加速高氯酸铵(AP)的热分解。实验结果表明，1在炸药和推进剂领域具有潜在的应用前景。
A new solvent‐free energetic MOF, [Pb(HBTI)]n(1) (H3BTI=4,5‐bis(1H‐tetrazole)‐1H‐imidazole), has been synthesized under hydrothermal and acidic conditions. It was characterized by elemental analysis, IR, thermogravimetric, differential scanning calorimetry (DSC) and SEM. Single crystal X‐ray diffraction analysis revealed that1features a rigid 3D framework architecture free of solvent molecules. Thermal analysis demonstrated that the thermostability of1was up to 325 °C. Non‐isothermal kinetic and apparent thermodynamic parameters of exothermic decomposition process of1were determined by Kissinger's and Ozawa's methods. Through oxygen‐bomb combustion calorimetry, the standard molar enthalpy of formation of1was determined. The calculated detonation properties (heat of detonation, detonation velocity and detonation pressure) and sensitivity tests of1were carried out. In addition,1was explored as combustion promoter to accelerate the thermal decompositions of ammonium perchlorate (AP) by differential scanning calorimetry. Experimental results indicated that1possesses potential application prospects in the field of explosives and propellants.
