Conjugated hybrid structures (conductive metallopolymers) designed by incorporating transition metals into conductive polymers can increase the properties of both materials and eliminate the disadvantages of materials for final applications to achieve the desired optical and electrical properties. Here in, S,S’-substituted vicinal dithioglyoxime and its mononuclear cobalt(II) complex has been synthesized and this pseudo macrocyclic Co(II) complex has been converted to full macrocycle by replacement of the hydrogen atoms with BF2+ moieties which act as strong electron-withdrawing units to enhance stability of the transition metal and to increase solubility of the macrocycle in common organic solvents. After electrochemical polymerization, polycarbazole based cross-linked conductive metallopolymer with caged metal centers have been achieved. As a consequence of the optical and electrochemical characterization of the unique structure, the highest optical contrast value was obtained among the polycarbazole derivatives in the literature. Electrochemical polymerization and electrochemical properties of the conducting metallopolymer have been also investigated with EQCM studies.

咔唑取代的不寻常钴(II)二肟配合物的合成,以设计具有笼状金属中心的导电聚合物,以增强光学和电学性质

通过将过渡金属掺入导电聚合物中而设计的共轭杂化结构(导电金属聚合物)可以提高两种材料的性能,并消除材料在最终应用中获得所需光学和电性能的缺点。在此,合成了S,S'-取代的邻位二硫代乙二肟及其单核钴(II)配合物,并且该伪大环Co(II)配合物已通过用BF2 +部分取代而取代为完整的大环,吸电子单元,以增强过渡金属的稳定性并增加大环在普通有机溶剂中的溶解度。在电化学聚合之后,已经获得了具有笼状金属中心的基于聚咔唑的交联导电金属聚合物。由于独特结构的光学和电化学特性,在文献中的聚咔唑衍生物中获得了最高的光学对比度值。导电金属聚合物的电化学聚合和电化学性能也已通过EQCM研究进行了研究。
