摘　　要：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1.61×10-6S.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。The DABT was synthesized with 2,3-butanedione, liquid dibromine and thiourea, and the ferrocenyl schiff base was synthesized by DABT and ferrocenecarboxaldehyde. Then polymer of ferrocenyl schiff base was prepared by the Friedel-Crafts method, their metal complexes were made by doping Fe^2＋ , Ni^2＋ and Cu^2＋ sulfates. Their structures were characterized by infrared spectra and ^1 HNMR spectra, conductivity and magnetism properties were measured with a Four-point probe Instrument and gouy magnetic balance. The experiment results showed that the synthetical product was polymer of ferrocenyl schiff base, its conductivity was 1.61× 10^-6 S· cm^-1 belonging to semiconductor. Magnetism properties of metal complexes by doping Fe^2＋ , Ni^2＋ and Cu^2＋ sulfates were obviously higher than polymer of un-doping, and properties of complexes by doping Cu^2＋ sulfate was best. These porperties indicated they can be applied as a new organic functional electromagnetism material.
