Abstract

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.
