Abstract:Pyrazoline derivatives have been investigated in many aspects due to their blue light emission with high quantum yield,ready accessibility,and easily being used as carrier transporting as well as emitting materials. According to Schellhammer theory of the relation between chemical structure and fluorescent quality,we designed some new fluorescent compounds with the benzothiazoyl group in the 1-pyrazoline,the derivatives of phenyl in the 3-pyrazoline and the furan in the 5-pyrazoline,and they possess fluorescent nature. In addition,the results of our research have shown that the benzothiazoyl derivatives can also be used for electroluminescence devices. Several benzothiazoyl pyrazoline compounds were synthesized,and their structures were confirmed by IR,1H NMR,fluorescence spectrum and elementary analysis. The fluorescence spectra showed that these compounds have good fluorescence. The fluorescence emission wavelengths are about 440-460 nm,and the fluorescence intensity is related to the substituent of the compounds.
