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
In absolute ethanol medium prepared with Fe3 + as the center metal ions, organic small molecule tetrathiafulvalene tetrathiol ttftt4- as a ligand, transition metal or rare earth ions as a counter-cation conductive coordination polymer compounds. The composition of the compound is represented by [(Fe ttftt) Mx] n (M = Co, Ni, Cu, Hg; x = 1.2,0.5,0,07,0.9) and [(Fe ttftt) Lny] n = Nd, y = 0.3; Ln = Sm, Eu, Tb, y = 0.4). They are all amorphous powdery solids that are stable and poorly soluble in the air. The properties of these compounds were investigated by elemental analysis, infrared spectroscopy, thermal analysis and Mossbauer spectroscopy. The powder conductivity of these compounds was determined by bipolar pressing at room temperature. The experimental results show that the nature of the countercation has an important effect on the powder conductivity of the polymer with iron as the central metal ion and that the countercation affects its conductivity mainly by affecting the structural symmetry of the polymer chain
