The synthesis of a water-soluble polycobaltoceniumylmethylene chloride (PCM-Cl) via ring-opening transmetalation polymerization is presented. Starting from a carba[1]magnesocenophane and cobalt(II) chloride, this route gives access to a polymer with methylene-bridged cobaltocenium moieties within the polymers' main-chain. The polymer was characterized by NMR spectroscopy, elemental analysis, TGA, DSC, XRD, and CV measurements, as well as UV-vis spectroscopy. Furthermore, GPC measurements in an aqueous eluent versus pullulan standards were conducted to gain insight into the obtained molar masses and distributions. In addition, the ion-dependent solubility was demonstrated by anion exchange, tuning the hydrophobic/hydrophilic properties of this redox-responsive material.
介绍了通过开环金属转移聚合合成水溶性聚钴茂亚甲基氯化铵（PCM-Cl）的方法。从碳[1]镁茂并环戊二烯和氯化钴（II）出发，该路线可得到主链中含有亚甲基桥连钴茂部分的聚合物。通过核磁共振光谱、元素分析、热重分析（TGA）、差示扫描量热法（DSC）、X射线衍射（XRD）、循环伏安（CV）测量以及紫外可见光谱对聚合物进行了表征。此外，在水性洗脱液中相对于支链淀粉标准品进行了凝胶渗透色谱（GPC）测量，以深入了解所获得的摩尔质量和分布情况。此外，通过阴离子交换证明了离子依赖性溶解度，调节了这种氧化还原响应材料的疏水/亲水性质。
