2-取代硫醚-5-(5-苯基-1H-3-吡唑基)-1,3,4-噁二唑类化合物的合成及光学性能研究
摘要:
以5-苯基-1H-3-吡唑甲酰肼为起始原料,经与二硫化碳环合和巯基烷基化两步反应,合成了5个新型的2-取代硫醚-5-(5-苯基-1H-3-吡唑基)-1,3,4-噁二唑类化合物,其结构经IR,~1 H NMR表征.光学性能研究表明目标产物具有良好的荧光性,其最大发射波长在344~347nm范围内.
Based on the starting material 5-phenyl-1H_pyrazole-3- carbohydrazide by cyclization and thioetherifi- cation five novel 2 - alkylthio - 5 - (5 - phenyl - 1H - pyrazole - 3 - yl) - 1,3,4 - oxadiazole derivatives were synthesized. Their structures were characterized by IR and 1 H NMR. Its UV absorption spectrum and fluorescent properties were investiga-ted. The results indicates these compounds have good fluorescent properties, and the maximum emission wavelength is in 344 - 347 nm range.
