以丁二酮、液溴和硫脲为原料经过有机合成反应制得2,2′-二氨基-4,4′-联噻唑(DABT);利用合成的DABT和二茂铁甲醛通过缩合反应得到小分子二茂铁席夫碱,利用傅列德尔-克拉夫茨反应原理制备了聚合二茂铁席夫碱;再将金属铁、镍和铜的硫酸盐掺杂聚合物得到其金属配合物,利用红外、1H核磁表征了产物的结构,用四探针测试仪和古埃磁天平测试了产物的电导率和磁性能.实验结果表明:合成产物是聚合二茂铁基席夫碱,其电导率为1.61×10-6 S·cm-1,处于半导体范围;掺杂有Fe2+,Ni2+和Cu2+的硫酸盐配合物的磁增重均比未掺杂的聚合物有明显的提高,其中掺杂Cu2+金属离子的配合物性能最好,这暗示它可作为一类新型的有机功能电磁材料.
