| 中文摘要: |
| 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，得到了三种不同颜色和不同构型的三种异构体。通过XRD、IR、1HNMR粉末衍射等表征手段确定了这几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，将该化合物与高分子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。 |
| 英文摘要: |
| 1, 3-Diphenyl-5-pyrazolone (DPP) was recrystallized from three different solvents, three isomers with different color were obtained. Their composition and structures were characterized by IR, 1H NMR, X-ray powder diffraction analysis. Their emission behaviors were studied by fluorescence spectra. The results indicate that these isomers exhibit the aggregation-induced emission behavior and photoisomerization. Moreover, the solvent obviously affects the structures and fluorescence of products. In addition, composite film also exhibits the good fluorescence, which has potential application in the field of antifake. |
