合成了一种联噻唑聚合物SPD及其Cu2＋配合物。探索了温度和反应时间对SPD产率的影响。利用红外、元素分析、X射线能谱仪对其结构进行了表征。研究显示,在100℃温度下反应6h,产率达最大,为79.5%。热重分析表明聚合物具有较好的热稳定性。常温下测定SPD和SPD-Cu2＋的电导率和磁滞回线,结果表明SPD配位Cu2＋后电导率下降。SPD是一种反铁磁体;SPD-Cu2＋是一种软铁磁体,矫顽力为5.25kA/m,剩余磁场强度为0.00105A·m2/kg,饱和磁化强度为0.029A·m2/kg。

The polymer (SPD) and its complex of Cu2+ were prepared and the effects of the temperature and time of reaction on the yield were investigated. Their structures were characterized via IR, elemental analysis and EDS. The study indicated: discovered on the temperature of 100℃ and reaction 6h later the maximum yield of SPD was 79.5%. The thermogravimetric analysis suggested that the polymer had good thermal stability. The electrical conductivity and hysteresis loop of the polymer and its complex were measured at room temperature. The test result demonstrate: the conductivity of complex was declined when coordinated with Cu2+; SPD was an antiferromagnet while SPD-Cu2+ was a soft ferromagnet, in which the observed coercive field (Hc) was 5.25kA/m, the remnant magnetization (Mr) was 0. 00105A·m2/kg and the saturation magnetization (Mc) 0. 029A · m2/kg.
