本文以1,3-二苯基-5-吡唑啉酮(DPP)为研究对象,采用不同溶剂对其进行重结晶,得到了3种不同颜色和不同构型的异构体。通过XRD粉末衍射、IR、1H NMR等确定了3种异构体的组成和结构,通过荧光光谱研究了它们的发光行为。结果表明这类化合物具有聚集诱导发光性能和光异构化性能,而且溶剂对产物的构型及发光性能均有明显的影响。此外,将该化合物与无规聚苯乙烯复合制备的薄膜也具有很好的荧光性能,在防伪领域具有潜在的应用。
In this paper, 1,3-diphenyl-5-pyrazolone (DPP) as the research object, using different solvents for its recrystallization, obtained three different colors and different configuration isomers. The structures and structures of three isomers were confirmed by XRD, IR and 1H NMR. Their luminescence behaviors were studied by fluorescence spectroscopy. The results show that these compounds have aggregation-induced luminescence and photoisomerization properties, and the solvent has a significant effect on the product configuration and luminescent properties. In addition, the compound prepared with random polystyrene film also has good fluorescence properties, has potential applications in the field of anti-counterfeit.
