【摘要】：传统的含能材料检测方法主要是基于化学传感和精密仪器测量,但这两种方法通常很难实现爆炸物的快速检测。近十多年来,在超分子材料和配位化学交叉领域,出现了一种新材料——光功能金属有机骨架材料(LMOFs),这种材料具有多孔性、高量子产率和稳定性等特征,被认为是一种优良的发光材料。一方面,LMOFs结合了有机发光材料和金属发光材料的优势,并通过骨架内能量传递提高体系的发光效率。另一方面,LMOFs具有的整齐的孔道结构及大的比表面,有利于对不同爆炸物分子的选择性识别。因此LMOFs在分子荧光识别和检测爆炸物方面展示了较好的应用前景。系统介绍了硝基类爆炸物、氮杂环爆炸物和非含氮爆炸物三类LMOFs在爆炸物识别和检测方面的研究进展,着重总结了LMOFs的识别机理和识别选择性。未来,LMOFs对爆炸物检测的研究可能更加重视材料的表面修饰、水稳定性提高和氮杂环爆炸物检测等方面的探索。
[Abstract]:The traditional detection methods of energetic materials are mainly based on chemical sensing and precision instrument measurement, but these two methods are usually difficult to achieve rapid detection of explosives. In the past decade or so, a new kind of material has emerged in the field of supramolecular materials and coordination chemistry. This material has the characteristics of porosity, high quantum yield and stability. It is considered to be an excellent luminescent material. On the one hand, LMOFs combine the advantages of organic luminescent materials and metal luminescent materials, and improve the luminescence efficiency of the system through energy transfer within the framework. On the other hand, LMOFs have neat pore structure and large specific surface, which is beneficial to the selective recognition of different explosive molecules. Therefore, LMOFs are promising in molecular fluorescence recognition and detection of explosives. The research progress of nitro explosives, nitrogen heterocyclic explosives and non-nitrogen explosives in the field of explosive identification and detection is introduced. The recognition mechanism and selectivity of LMOFs are summarized in detail. In the future, LMOFs may pay more attention to the surface modification of materials, the improvement of water stability and the detection of nitrogen heterocyclic explosives.
