【摘要】：含能金属有机骨架(E-MOFs)兼具高能量和低感度的特征,近几年受到各国相关科研工作者的广泛关注。设计合成结构新颖、能量特征优异和安全性能良好的新型E-MOFs已成为含能材料领域的研究热点。用于构筑E-MOFs材料的配体分子可概括为:含能小分子配体、富氮杂环类配体和高能多致爆基配体三大类。按上述分类方法,从E-MOFs材料的结构构筑方式、能量水平、安全性等方面出发,对近年来E-MOFs材料的最新研究进展进行了综述。系统梳理E-MOFs材料的最新成果发现,富氮类多齿含能配体的设计和选择及其与中心金属离子的有序自组装是构筑具有新颖结构E-MOFs材料的关键,不同的自组装方式决定了E-MOFs材料的空间拓扑结构,极大地影响着其物理化学性能。作为一类新兴的含能材料,E-MOFs材料的高能低感特性使其在固体推进剂配方、近激光起爆等领域展现出一定的研究价值和发展潜力。
[Abstract]:E-MOFs have the characteristics of high energy and low sensitivity. In recent years, E-MOFs have attracted wide attention from researchers in various countries. The design and synthesis structure of E-MOFs is novel. Novel E-MOFs with excellent energy characteristics and good safety performance has become a research hotspot in the field of energetic materials. The ligands used in the construction of E-MOFs materials can be summarized as follows: ligands with small molecules of energy. According to the above classification method, the structure, energy level and safety of E-MOFs materials are analyzed. In this paper, the latest research progress of E-MOFs materials in recent years is reviewed. The design and selection of nitrogen-rich polydentate ligands and their ordered self-assembly with central metal ions are the key to the construction of novel E-MOFs materials. Different self-assembly methods determine the spatial topological structure of E-MOFs materials. The physical and chemical properties of E-MOFs are greatly affected. As a new kind of energetic materials, E-MOFs exhibit a certain research value and development potential in the field of solid propellant formulation, near laser detonation and so on.
