摘　　要：设计合成了含哌嗪基团的咔唑衍生物,N,N′-二[3-(N-咔唑)苯基]-哌嗪.在溶液中该化合物具有很强的蓝色荧光和高的量子产率为0.94,可作为荧光材料.在水和N,N-二甲基甲酰胺(DMF)的混合溶液中随溶液的pH值的降低而降低,化合物的最大发射峰降低幅度达到了94%.荧光的降低是由于化合物中的N原子与质子的结合引起的,实验结果表明,合成的化合物可以作为质子的荧光化学传感器.A novel piperazine-containing carbazole derivative,N,N′-di[3-（N-carbazole）benzyl]-piperazine（DC-Pip）,was designed and prepared.The absorption and fluorescence maxima of DC-Pip were observed at 300 and 405 nm,respectively.DC-Pip emits strong blue fluorescence and has a high quantum yield（ΦF=0.94） in solution,which indicates that DC-Pip can be used as fluorescence emitting materials.The effect of pH on the fluorescence characteristics of DC-Pip in H2O/DMF（4∶1,V/V） solution has also been investigated,the intensity of fluorescence decreases with the decrease of pH value,these results shows that DC-Pip offers potential as optical sensor for protons.
