The development of synthetic organic polymers during the last century had a tremendous impact on the advancement of society. To date, our modern life would be unthinkable without carbon-based polymers. However, as approximately 80% of all chemical elements are metals, there remains an enormous potential for the application of new metal-containing polymers, so-called metallopolymers. As many small molecules, extended solids, and biological systems owe their interesting and useful properties to the presence of metals, early on, scientists were fascinated by the idea of assembling metals into polymers. However, this area of polymer chemistry had been held back for many decades because of challenging problems, such as synthetic procedures, purification issues, lack of suitable starting materials, and characterization issues. Many of these issues have been resolved or improved upon during the last two decades so that some applications of metallopolymers have started to emerge. Despite the impressive progress in this area, there is a pressing need to develop new monomers and polymerization methodologies and protocols so that the enormous potential that the periodic table of elements offers for metallopolymers can be realized in the decades to come. This discovery grant research program addresses the current shortcomings of polyferrocene chemistry by proposing the preparation of new strained sandwich compounds. These species will be used for the fabrication of new metallopolymers.

上个世纪合成有机聚合物的发展对社会的进步产生了巨大的影响。到目前为止，如果没有碳基聚合物，我们的现代生活将是不可想象的。然而，由于所有化学元素中约80%是金属，因此新的含金属聚合物（所谓的金属聚合物）的应用仍具有巨大的潜力。由于许多小分子，扩展固体和生物系统都将其有趣和有用的特性归功于金属的存在，因此早期，科学家们对将金属组装成聚合物的想法非常着迷。然而，由于具有挑战性的问题，如合成程序，纯化问题，缺乏合适的起始材料和表征问题，聚合物化学的这一领域已经被搁置了几十年。在过去的二十年中，这些问题中的许多已经得到解决或改进，因此金属聚合物的一些应用已经开始出现。尽管在这一领域取得了令人印象深刻的进展，但迫切需要开发新的单体和聚合方法和方案，以便在未来几十年内实现元素周期表为金属聚合物提供的巨大潜力。这项发现补助金研究计划通过提出新的应变三明治化合物的制备来解决聚二茂铁化学目前的缺点。这些物种将用于制造新的金属聚合物。
