Cationic Cobaltocenium Polyelectrolyte Polymers: Synthesis, Self-Assembly and Utilities

在这项由化学系高分子、超分子和纳米化学计划资助的项目中，南卡罗来纳大学的唐传兵将探索含钴镉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。该方法是通过控制含钴单体聚合和聚合后修饰的方法合成和表征含钴聚合物：研究含钴嵌段共聚物的组装，探索钴氧化物纳米粒子的模板合成；为了对电池电极中含钴聚合物的使用进行初步研究，更广泛的影响包括培训本科生和研究生进行研究，通过出版物和在会议上的演讲广泛传播研究成果，以及参与针对高中生、本科生和研究生的综合教育活动，以通过加强全球研究和教育培训机会激发他们对科学和技术的兴趣。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、汽车和航空航天运输的结构材料，以及轻型电子设备。这项研究将探索在聚合物结构中包括金属原子的新方法，这可能会影响聚合物的电学性能，并可能导致用于轻质、灵活的电化学电池的材料。这种含金属的聚合物还可以用来制作具有重要技术意义的磁性或催化纳米粒子(尺寸在1到100纳米量级的小块材料，大约是人类头发宽度的1万倍)的模板。

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).
