Abstract and Keywords

Abstract: The recognition and detection of explosive compounds are related to the safety of the environment and human beings, which have become one of the hotspots of current scientific research. In this work, a crystalline material 1 was designed and assembled by using a bifunctional organic bridging ligand containing urea and carboxyl groups and metal zinc ions. The structure and properties of the crystalline compound were characterized by X-ray diffractometer (XRD), thermogravimetric analyzer (TGA), Fourier transform infrared spectroscopy (FTIR), and fluorescence spectroscopy. It is found that crystalline material 1 is a metal-organic framework material crystallized in the monoclinic $ P2_{1}/c $ space group, which has 68.3% internal pores, open molecular channels, and abundant hydrogen-bonding sites. As a sensing material, it is capable of effective detection of explosive nitro compounds such as picric acid.

Keywords: metal-organic framework; hydrogen-bonding functional site; explosive compounds; fluorescence detection

摘要和关键词

摘要: 爆炸性化合物识别检测关系到环境和人类的安全,是当前科学研究的热点之一。文章利用一种含有脲基和羧基的双功能有机桥联配体与金属锌离子设计并组装一种晶态材料1,采用X-射线衍射仪(X-ray diffractometer, XRD)、热重分析仪(thermal gravimetric analyzer, TGA)、傅里叶变换红外光谱仪(Fourier transform infrared spectroscopy, FTIR)和荧光光谱仪等对其结构和性能进行分析。研究结果表明,晶态材料1是一种结晶于单斜晶系 $ P2_{1}/c $空间群的金属有机框架材料,其具有68.3%的内部孔隙、开放的分子通道和丰富的氢键位点,因此晶态材料1可作为一种传感材料来检测苦味酸等爆炸性硝基化合物。

关键词: 金属-有机框架；氢键功能位点；爆炸性化合物；荧光检测
