金属有机骨架锌化合物的微波合成与荧光传感性能
|
摘要
采用微波合成法制备了金属有机骨架材料1,通过IR和N2吸附对其结构进行表征,表明该材料为目标产物。此外,研究了该材料对多种溶剂的荧光作用。结果表明硝基苯的猝灭作用最强,因此该材料对芳香硝基化合物具有一定的选择性。
The material 1 was synthesized by a modified microwave method, which were also characterized by IR and adsorption of N2. The results showed that all samples were the single pure phase. On the other hand, the influence of the quality with organic solvent, and nitroaromatic compounds quenching by nitroben-zene(NB) was also investigated. The experimental results exhibited that the nitrobenzene is favorable for the fluorescence quenching of compound 1, andwhich also shows the selective and sensitive detection of nitroaromatics.
