系列氮唑类含能配合物的合成及其性质

The Synthesis and Properties of a Series of Energetic Coordination Polymers Based on Azole Derivatives

  • 摘要: 氮唑类金属配合物是含能材料中研究较为广泛的一类材料,其结构易于调控,且具有高能低感的特性。本文选用1,2,4-三氮唑、四氮唑和5-氨基四氮唑这三类配体,与Zn2+、Cd2+、Cu2+等金属离子合成得到系列金属有机骨架结构,并对这些物质进行了热重、差热分析和燃烧热性能测试,结果表明金属离子参与配位后,氮唑类配合物的热稳定性得到了明显增强,其密度也随之增加,而热能数据表明合适的金属离子与含能配体参与配位能有效提高含能配合物的标准摩尔生成焓,金属离子与有机配体的配位聚集程度对生成焓有一定的影响作用,这对今后如何选择合适的金属离子与含能配体进行含能配合物的合成具有指导意义.

     

    Abstract: The coordination polymers based on azole ligands are one of the most attractive energetic materials at recent years because of their tunable structures, high energy and low sensitivity. In this work, three kinds of azole ligands, 1,2,4-triazole, tetrazole and 5-aminotetrazole, were chosen to construct series of metal organic frameworks with different metal ions such as Zn2+, Cd2+ and Cu2+. Furthermore, These materials have been measured with thermogravimetry, differential Scanning Calorimeter and oxygen bomb tests, which show that the stabilities of the coordination polymers and densities have been enhanced obviously. The enthalpies of formation could be affected by the accumulation between suitable metal ions and energetic ligands, it is instructive for the synthesis of high energetic coordination polymers in future.
