采用开环聚合技术制备了水溶性高分子量聚二茂钴聚电解质。应变19-电子二碳[2]cobaltocenophane的阴离子聚合，然后在氯化铵的存在下氧化，导致形成的低聚物与多达9个重复单元。二碳[2]二茂钴烷的热ROP随后在硝酸铵的存在下氧化，导致形成高分子量的聚二茂钴硝酸盐，一种氧化还原活性的含钴化合物。
Water-soluble, high-molecular-weight polycobaltocenium polyelectrolytes have been prepared by ring-opening polymerization (ROP) techniques. Anionic polymerization of a strained 19-electron dicarba[2]cobaltocenophane followed by oxidation in the presence of ammonium chloride resulted in the formation of oligomers with up to nine repeat units. Thermal ROP of dicarba[2]cobaltocenophane followed by oxidation in the presence of ammonium nitrate resulted in the formation of high-molecular-weight polycobaltocenium nitrate, a redox-active cobalt-containing polyelectrolyte.
