一种新型刚性MOFs对硝基芳香化合物的荧光检测研究

Fluorescence detection of nitroaromatic compounds by a new type of rigid MOFs

MOFs由于具有丰富的孔道结构,在储能、催化和分离等领域都有广泛应用。文章通过水热法合成了一种刚性三维MOFs:Zn-MOF。该材料表现出优异的荧光性能,经检测对实验所用6种硝基芳香化合物均有不同程度的荧光淬灭现象。Zn-MOF对2,4-DTP和4-N-3-MP荧光淬灭效果明显,可应用于对应硝基芳香化合物的检测。

MOFs are widely used in energy storage, catalysis and separation due to their rich pore structure. In this paper, a rigid three-dimensional MOFs as Zn-MOF was synthesized by hydrothermal method. The material exhibits excellent fluorescence properties, and has different degrees of fluorescence quenching phenomenon for the six nitroaromatic compounds used in the experiment. Zn-MOF has obvious fluorescence quenching effect on 2,4-DTP and 4-N-3-MP, which can be applied to the detection of corresponding nitroaromatic compounds.
