后官能化是一种有效的策略来调整共轭聚合物的性能，而在共轭主链的主链上的聚合物反应仍然是探索不足。在这里，我们报告的后官能化的共轭聚合物的主链通过亲核芳香取代反应。聚（9，9-二辛基芴-交替-邻-对亚苯基）用作前体，在碱存在下与苯硫酚衍生物反应，以使得能够以高产率将芳硫基多次引入聚合物主链中，同时保持前体聚合物的主链和分散性。所得聚合物的主链结构和光电性能显着改变，证明了模型化合物和聚合物的光谱分析以及计算机模拟。
Postfunctionalization is a useful strategy to tune the properties of conjugated polymers, while polymer reactions in the main chain of a conjugated backbone are still underexplored. Here we report the postfunctionalization of the main chain of a conjugated polymer via nucleophilic aromatic substitution reaction. Poly(9,9-dioctylfluorene-alt-tetrafluoro-p-phenylene) is used as a precursor to react with thiophenol derivatives in the presence of a base to enable multiple introduction of arylthio groups into the polymer main chain in high yield with preserving the backbone and the dispersity of the precursor polymer. The main chain structure and optoelectronic properties of the resulting polymers were significantly changed, evidenced by spectroscopic analysis of both model compounds and polymers as well as a computational simulation.
