| 摘 要： | 以对苯二甲醛和4,4’-二氨基偶氮苯衍生物为原料合成得到了3种含偶氮基聚席夫碱化合物,并利用红外光谱、紫外-可见吸收光谱及荧光光谱进行了表征.结果表明,取代基为-OH时聚合物最大紫外吸收波长λmax最大,荧光光谱显示3种聚合物荧光性都比较弱.采用不含偶氮基的类似结构的聚席夫碱化合物作对照,表明偶氮基团的引入减弱了聚合物的荧光性. |
| 关 键 词： | 偶氮基团 聚席夫碱 合成 |

| Abstract: | Three polyschiff’s bases containing azo group were synthesized by p-phthalaldehyde and 4,4’-azodianiline and its derivatives as basic materials,the products were characterized by IR,UV-visible and fluorescent spectra.It was shown that the maximum absorbed wavelength λmax of the polymer containing-OH is bigger than the others,and that all the three polyschiff’s bases synthesized have weak fluorescent radiation.Comparison of the fluorescence of polyschiff’s bases containing azo groups with polyschiff’s bases without azo groups indicates that azo groups weaken the fluorescence of polyschiff’s bases. |
| Keywords: | azo group polyschiff’s base synthesis |
