摘要：Novel pyrazoly 1,3,4-oxadiazole derivatives were synthesized and characterized by ~1H 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 1max and emission λ_(max) was less correlated with substituent groups on aryl rings.
