In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Chuanbing Tang of the University of South Carolina will explore the synthesis and properties of cobaltocenium-containing polymers, the isoelectronic analogues of the more widely studied ferrocene-containing macromolecules. The approach is to synthesize and characterize cobaltocenium-containing polymers by controlled polymerization of cobaltocenium-containing monomers and by post-polymerization modification routes; to study the assembly of cobaltocenium-containing block copolymers and explore the template synthesis of cobalt oxide nanoparticles; and to perform preliminary studies into the use of the cobaltoceneum-containing polymers in battery electrodes The broader impacts involve training undergraduate and graduate students in research, broadly disseminating research results through publications and presentations at conferences, as well as participating in integrated educational activities for high school, undergraduate and graduate students to stimulate their interest in science and technology with enhanced global research and education training opportunities.Plastics are long chain organic molecules and are found in many facets of everyday life, including food packaging, structural materials for automotive and aerospace transportation, and lightweight electronic devices. This research will explore new approaches to include metal atoms within the polymer structure, which can impact the polymer's electrical properties and potentially lead to materials for light-weight, flexible electrochemical batteries. The metal-containing polymers could also be used to template the creation of technologically important magnetic or catalytic nanoparticles (small pieces of material with dimensions on the order of 1 to 100 nanometers, which is about 10,000 times smaller than the width of a human hair).

在这个由化学系大分子，超分子和纳米化学项目资助的项目中，南卡罗来纳州大学的Chuanbing Tang将探索含钴聚合物的合成和性质，这是更广泛研究的含二茂铁大分子的等电子类似物。 方法是通过含二茂钴单体的控制聚合和聚合后改性路线合成和表征含二茂钴聚合物;研究含二茂钴嵌段共聚物的组装，探索氧化钴纳米颗粒的模板合成;并对钴矿的用途进行初步研究，在电池电极中含有聚合物更广泛的影响包括在研究中培训本科生和研究生，通过出版物和会议上的演讲广泛传播研究成果，以及参与高中生、本科生和研究生的综合教育活动，以激发他们对科学和技术的兴趣，增加全球研究和教育培训机会。塑料是长链有机分子，存在于日常生活的许多方面，包括食品包装，用于汽车和航空航天运输的结构材料以及轻质电子器件。 这项研究将探索在聚合物结构中包含金属原子的新方法，这可能会影响聚合物的电性能，并可能导致轻质，柔性电化学电池的材料。 含金属的聚合物还可以用于制造技术上重要的磁性或催化纳米颗粒（尺寸在1到100纳米之间的小块材料，比人类头发的宽度小10，000倍）。
