【摘要】 在绝对乙醇介质中制备出以Fe3 + 为中心金属离子、有机小分子四硫富瓦烯四硫醇盐ttftt4-作为配体、过渡金属或稀土离子作为抗衡阳离子的导电性配位高分子化合物。化合物的组成为 [(Fe ttftt)Mx] n(M =Co、Ni、Cu、Hg ;x =1.2、0 .5、0 .7、0 .9)及 [(Fe ttftt)Lny] n(Ln =Nd ,y =0 .3;Ln =Sm、Eu、Tb ,y =0 .4 )。它们均为能够在空气中稳定存在且难溶的无定形粉末状固体。用元素分析、红外光谱、热分析和穆斯堡尔谱对化合物的性质进行了研究 ,并在室温下用双极压片法测定了该类化合物的粉末电导率。实验结果表明 ,抗衡阳离子的性质对以铁作为中心金属离子的聚合物的粉末电导率有着重要的影响 ,而且抗衡阳离子主要是通过影响聚合物链的结构对称性来影响其导电性能更多还原

【Abstract】 Two series of polymers based on iron complexes of the tetrathiafulvalenetetrathiolate (ttftt 4- ) of the stoichiometry [(Fe ttftt)M x] n(M=Co,Ni,Cu,Hg; x =1.2,0.5,0.7,0.9) and [(Fe ttftt) Lny] n (Ln=Nd, y = 0.3; Ln=Sm,Eu,Tb, y =0.4) are prepared in absolute ethanol. These insoluble amorphous polymeric complexes have been characterized by elemental analysis, IR spectra, TG DTA techniques, Mssbauer spectroscopy and conductivity measurements. The spectroscopicresults are discussed in relation to the structure of these compounds. In the Mssbauer spectra of the investigated complexes, the isomer shift shows trivalent iron ions as the main component in the samples, and the quadrupole splitting is typical for distorted octahedral coordination geometry. The complexes behave as semiconductors at 25℃ as compacted pellets.更多还原
