Templated polymerization is a process whereby the molecular weight and dispersity of a parent polymer can be mirrored onto a second, daughter polymer. While ubiquitous in nature and explored in bio-inspired polymers, templated synthesis has scarcely been used towards the controlled synthesis of conjugated polymers. Conjugated polymers are useful for electronic and optical applications, yet very few examples can be prepared in a controlled manner. Here we show that it is possible to use ring-opening metathesis polymerization to prepare macromolecular templates with controlled molecular weights and dispersities. Chemical oxidative polymerization is then used to prepare the final well-defined conjugated polymers. By combining these techniques, we demonstrate a versatile approach to well-defined conjugated polymers, where traditional synthetic routes are generally limited in control and/or scope. Templated oxidative polymerization affords organic soluble, oxidatively doped PEDOT-based polymers with controlled molecular weights and low dispersities (Đ ∼ 1.2). To our knowledge, this is the first report of a templated approach being used to definitively control the molecular weight, dispersity, and solubility of conjugated polymers during oxidative polymerization.

定义明确的氧化偶联共轭聚合物的模板化方法

模板化聚合是一种可以将母体聚合物的分子量和分散度镜像到第二个子聚合物上的方法。虽然自然界中普遍存在，并且在生物启发的聚合物中得到了探索，但模板化合成几乎没有用于共轭聚合物的受控合成。共轭聚合物可用于电子和光学应用，但很少有实例可以控制方式制备。在这里，我们表明有可能使用开环复分解聚合来制备具有受控分子量和分散度的大分子模板。然后使用化学氧化聚合反应制备最终的明确共轭聚合物。通过结合这些技术，我们展示了一种用于定义明确的共轭聚合物的通用方法，传统的合成路线通常在控制和/或范围上受到限制。模板氧化聚合可提供有机可溶，氧化掺杂的PEDOT基聚合物，具有可控制的分子量和低分散性（Đ〜1.2）。据我们所知，这是模板化方法的首次报道，该方法用于确定性地控制氧化聚合过程中共轭聚合物的分子量，分散性和溶解性。
