摘　　要：以丁二酮、液溴和硫脲为原料合成了2,2-二氨基-4,4-联噻唑(DABT);将DABT与对氨基苯甲酸和多聚甲醛共聚制得对氨基苯甲酸缩聚DABT聚合物,然后与铁、镍、铜的硫酸盐配合得到金属配合物。表征了产物结构,测试了产物的热性能、电导率、磁性能和荧光特性。结果表明,对氨基苯甲酸缩聚DABT聚合物的电导率优于配合有金属离子的聚合物,其值为3.12×10-6S/cm,处于半导体范围;配合Fe2+的聚合物具有一定的磁性能,表明配合Fe2+聚合物是一种有机软铁磁体;而配合Cu2+的聚合物能激发产生荧光,具有发射紫外-蓝光特性,可作为新型有机光功能材料。The DABT was synthesized from 2,3-butanedione, liquid dibromine and thiourea; and the polymer of DABT polycondendation of p-aminobenzoic acid was synthesized by DABT, p-aminobenzoic acid and paraformaldehyde. Their metal complexes were prepared by doping Fe^2＋ , Ni^2＋and Cu^2＋ sulfates. Their structures were characterized by infrared spectra and ^1H-NMR spectra, thermal, electro-magnetic and fluorescence properties were measured. The experiment results show that conductivity of polymer is excelled their metal complexes, it is 3.12 × 10^-6 S/cm, belonging to semiconductor. Magnetism properties of metal complexes by doping Fe^2＋ , Ni^2＋ and Cu^2＋ are obviously better than polymer of un-doping, and property of Fe^2＋ -complexes is best. The Fe^2＋-complexes exhibits a typical ＂S＂ shape hysteresis cycle, the observed coercive fields is 130 Oe, and relative saturation magnetization and remnant magnetization is 0.612 emu/g and 0.0257 emu/g, respectively. The Fe^2＋-complexes is a soft ferromagnet and the Cu^2＋-oomplexes is a novel organic photic functional materials as it has properties of emission fluorescence and UV-blue.
