摘　　要：以2-苯基-1,2,3-三唑基-4-甲醛为原料,与苯乙酮或取代苯乙酮发生羟醛缩合生成相应的查尔酮;再与2-肼基苯并噻唑反应,合成了5个含1,2,3-三唑基、苯并噻唑基的新型吡唑啉衍生物,其结构经1HNMR、IR和元素分析表征。荧光性能研究结果表明:该类化合物具有良好的荧光性,其最大发射波长在427~444nm,荧光强度大小与衍生物中不同的取代基有关。The chalcone intermediates were synthesized via an aldol condensation reaction from 2-phenyl-1,2,3-triazolyl-4-formaldehyde with acetophenone,and then reacted with 2-hydrazinobenzothiazole to afford five novel pyrazoline derivatives containing 1,2,3-triazole moiety. The structures were characterized by 1 H NMR,IR and elemental analysis. The title compounds showed good fluorescence properties with the maximum emission wavelength between 427 and 444 nm,which were affected by the substitution group type. A red shift occurs in the electron withdrawing groups(such as Br,Cl),while a blue shift in the electron-donating groups(such as CH 3 ,OCH 3 ).
