合成了一种新的γ-(2-脲基噻唑)丙基甲基二乙氧基硅烷单体及聚硅氧烷聚合物,采用溶胶-凝胶法制备了聚硅氧烷的铜、镍金属离子的配合物,利用红外光谱、核磁共振氢谱及质谱等手段表证了其结构.并分析和讨论了它们的磁学性能.此类金属配合物在低温区,磁化率倒数与温度的关系不服从居里-外斯定律,存在着铁磁耦合,是一类有机铁磁体.另外,发现在含噻唑基团的硅氧烷链中引入5倍当量的二甲基硅氧烷链节,其居里-外斯温度增大了近2倍.
A new γ- (2-ureidothiazole) propylmethyldiethoxysilane monomer and polysiloxane polymer were synthesized. The polysiloxane copper, nickel Their structures were characterized by IR, 1HNMR and MS spectra, and their magnetic properties were also analyzed and discussed. In the low temperature region, the metal complexes were characterized by reciprocal of magnetic susceptibility and temperature The relationship does not obey the Curie-Weiss law, there is a ferromagnetic coupling, is a class of organic ferromagnetic.In addition, it was found in the thiazole group containing siloxane chain 5 times the equivalent dimethylsiloxane chain , Its Curie - Vassal temperature increased nearly 2 times.
