Novel pyrazoly 1,3,4-oxadiazole derivatives were synthesized and characterized by (1)H NMR, IR, HRMS and X-ray diffraction analysis. UV-vis absorption and fluorescence properties of these compounds in different solutions showed that the maximum absorption wavelength was not significantly changed in different solvents; however, maximal emission wavelength was red-shifted with the increase of solvent polarity. Absorption λ(max) and emission λ(max) was less correlated with substituent groups on aryl rings.
新型吡唑并[1,3,4-]噁二唑衍生物通过 1H NMR、IR、高分辨质谱和 X 射线衍射分析进行了合成和表征。这些化合物在不同溶液中的紫外可见吸收和荧光性质表明，最大吸收波长在不同溶剂中没有明显变化；然而，最大发射波长随着溶剂极性的增加而红移。吸收λ(max)和发射λ(max)与芳环上取代基的相关性较小。
