The goal of this research is to design new synthetic approaches to making macromolecules that incorporate metallic moieties in their structures. The presence of the metal will facilitate the gain/loss of electrons. The proposed materials will also have properties that are useful in the design of new materials, which foster developments in science and technology. For instance, the polymers capable of detecting carbon monoxide in the environment, encapsulating environmental pollutants such as lead(II), cadmium(II), mercury(II), and phenols, will be designed. We will also design a new synthetic route to polymers that harvest solar energy and use the energy to initiate the flow of electrons as an in electrical conductor. Some of the proposed polymers will have magnetic properties and bioactive properties, as well as high thermal stability. Although, many of these polymers are known and are obtained via laborious synthetic methods, we propose to synthesize these polymers via an innovative, a cost effective and simple method. Our success will greatly reduce the cost of these polymers. Most of these reactions will use iron-containing materials as a mediator since the reaction conditions are mild and the relatively low cost associated with the iron starting materials. Our research laboratory is equipped with the necessary instruments to synthesize and characterize the newly prepared monomers and macromolecules. Both undergraduate and graduate students involved in this research program will acquire the necessary skills that will contribute to the advancement of their future careers in industry or academia.

这项研究的目标是设计新的合成方法来制造在其结构中包含金属部分的大分子。金属的存在将促进电子的得/失。拟议的材料还将具有在新材料设计中有用的特性，从而促进科学和技术的发展。例如，将设计能够检测环境中一氧化碳的聚合物，封装铅（II）、镉（II）、汞（II）和酚类等环境污染物。我们还将设计一种新的合成聚合物的途径，这种聚合物可以收集太阳能，并利用这些能量启动电子的流动，作为导电体。一些提出的聚合物将具有磁性和生物活性，以及高热稳定性。虽然这些聚合物中有许多是已知的，并且是通过费力的合成方法获得的，但我们建议通过一种创新的、成本有效的、简单的方法来合成这些聚合物。我们的成功将大大降低这些聚合物的成本。这些反应大多使用含铁材料作为介质，因为反应条件温和且铁起始材料成本相对较低。
