Synthesis and optical properties of two novel stilbene derivatives containing 1,3,4-oxadiazole moiety.
Two novel stilbene derivatives containing 1,3,4-oxadiazole moiety were synthesized and characterized by elemental analyses, (1)H NMR, MS. The photophysical processes of the title compounds were investigated by UV-vis absorption and fluorescence emission spectra in different solutions. The fluorescence quantum yield (Phi) of 1a and 1b in THF is 0.65 and 0.69, respectively. The influence of the solution on the fluorescence intensities was also discussed. Under ultraviolet light excitation, the two compounds exhibit strong blue fluorescence emission. They may serve as potential applications in organic electroluminescent materials.
