We describe a series of copolymerization studies whereby the nonbenzenoid aromatic methano[10]annulene is incorporated into three different types of random copolymers, two based on polythiophenes (from bithiophene and terthiophene monomers) and one based on poly(ethylene dioxythiophene). Copolymers where the annulene component was in the majority had optical and electrochemical behaviors reminiscent of the annulene homopolymer. In contrast, we found that the annulene influenced polymer electronics at very low feed ratios where the commercial comonomer was in the majority. Copolymerizations are useful approaches to dilute the complex annulene monomers into functional polymers without losing the optoelectronic properties of the annulene homopolymers. These electrochemical results provide important design rules that can be employed for the chemical synthesis of related random copolymers.
我们描述了一系列共聚研究,其中将非苯并芳烃甲撑[10]轮烯并入三种不同类型的无规共聚物中,两种基于聚噻吩(来自联噻吩和三噻吩单体),一种基于聚(乙二氧噻吩)。环烯成分占多数的共聚物具有类似于环烯均聚物的光学和电化学行为。相比之下,我们发现环烯在商业单体占多数的非常低的进料比下影响聚合物电子。共聚是将复杂的轮烯单体稀释到功能聚合物中而不损失轮烯均聚物的光电性能的有用方法。这些电化学结果提供了可以用于相关无规共聚物的化学合成的重要设计规则。
