Abstract Organic electroluminscent (OEL) technology has revealed the great potential application in flat panel display, and has attracted much interest all over the world. In order to create more efficient and high performance device, new materials with high electron transporting capability were demanded. Schiff base complexes can be employed as emitting materials to fabricate electroluminescent device. Several pyridine diacylhydrazones compounds were synthesized. The structure of compounds was confirmed by IR, fluorescence spectrum and elementary analysis. The fluorescence spectra showed that these compounds have good fluorescence. The fluorescence emission wavelengths are between 420 and 440 nm, the fluorescence intensity is related to the substituent of the compounds. The substituent of —OH, furan and piperonal donate electrons that lead to the red shift of fluorescence.
