含能配位聚合物作为固体推进剂的助燃剂具有良好的应用前景。本文以刚性无质子富氮配体1,3,5-三（1h -1,2,4-三唑-1-基）苯（TTB）和环境友好型铜离子为基础，采用阴离子调节策略，采用溶剂热法制备了两个ECPs {[Cu6(TTB)2(CN)6]·CH3CN}n(1)和{[Cu(TTB)(NO3)2]·CH3CN}n(2)。分别对两种ECPs的x射线晶体学分析、热稳定性、放热分解过程动力学参数、热安全性能、机械灵敏度和理论爆轰特性进行了探讨。同时，通过差示扫描量热法、热分解动力学和表面形貌分析，考察了它们对高氯酸铵燃烧分解的促进作用。实验结果表明，ecp2在固体推进剂领域具有良好的应用潜力。
Energetic coordination polymers (ECPs) have good application prospects as combustion promoters of solid propellants. In this work, based on a rigid proton-free nitrogen-rich ligand 1,3,5-tri(1H-1,2,4-triazol-1-yl)benzene (TTB) and an environmentally friendly copper ion, two ECPs, {[Cu6(TTB)2(CN)6]·CH3CN}n(1) and {[Cu(TTB)(NO3)2]·CH3CN}n(2), were prepared by the solvothermal method using an anion regulation strategy. X-ray crystallographic analyses, thermal stability, kinetic parameters of exothermic decomposition process, thermal safety performances, mechanical sensitivity, and theoretical detonation characteristics of two ECPs were, respectively, explored. Meanwhile, their promoting effects on the combustion decomposition of ammonium perchlorate were investigated by differential scanning calorimetry tests, thermal decomposition kinetics, and surface morphology analyses. Experimental results indicated that ECP2has good application potential in the solid propellant field.
