π-conjugated macromolecules for organic polymeric solar cells can be rationally engineered at the molecular level in order to tune the optical, electrochemical and solid-state morphology characteristics, and thus to address requirements for the efficient solid state device implementation. The synthetic accessibility of monomers and polymers required for the device is getting increasing attention. Direct arylation reactions for the production of the π-extended scaffolds are gaining importance, bearing clear advantages over traditional carbon-carbon forming methodologies. Although their use in the final polymerization step is already established, there is a need for improving synthetic accessibility to implement them also in the monomer synthesis. In this review, we discuss recent examples highlighting this useful strategy.
用于有机聚合物太阳能电池的π共轭大分子可以在分子水平上进行合理设计，以调节光学、电化学和固态形态特征，从而满足高效固态器件实现的要求。该器件所需单体和聚合物的合成可及性正受到越来越多的关注。用于生产π扩展支架的直接芳基化反应正变得越来越重要，与传统的碳-碳形成方法相比具有明显优势。尽管它们在最终聚合步骤中的应用已经确立，但仍需要提高合成可及性，以便在单体合成中也能应用它们。在本综述中，我们讨论了突出这一有用策略的近期实例。
