摘　　要：通过取代苯甲醛和苯乙酮的羟醛缩合反应合成出了中间体查尔酮,然后,在微波辅助下,使查尔酮与苯肼反应合成了标题化合物,通过元素分析、红外光谱和1HNMR,对合成的化合物进行了表征,并测试了其荧光光谱,表明这类化合物具有良好的荧光性能,最大发射波长在430～450 nm范围,其荧光强度与衍生物中取代基团密切相关。Five intermediate chalcones were synthesized by the aldol condensation reaction of substituted benzaldehyde and acetophenone. And then, 1,3,5-triaryl-substituted pyrazo- line derivatives were synthesized by the reaction of chalcone and phenylhydrazine under the microwave-assisted. These compounds were characterized by elemental analysis, IR and I HNMR, and fluorescence spectra. These compounds have good fluorescent properties, and the maximum emission wave- length is in 430 - 450 nm range. And the fluorescence intensi- ty was related to the substituent groups of the derivatives.
