We report a step-saving new access to D-π-D-π-D type oligoaryls through one-pot sequential C-H (hetero)arylations. Conventionally, these oligomers were prepared by Stille or Suzuki coupling reactions that required prefunctionalization steps. The facilely synthesized linear oligomers were fabricated in perovskite-based solar devices as efficient hole transporters, exhibiting a power conversion efficiency of up to 15.4%.
我们报告了一种通过一锅顺序 C-H（杂）芳基化反应来简便制备 D-π-D-π-D 型寡芳基的新方法。传统上，这些寡聚物是通过 Stille 或 Suzuki 偶联反应制备的，这些反应需要预官能化步骤。我们将通过简便方法合成的线性寡聚物作为高效空穴传输体应用于钙钛矿基太阳能器件中，实现了高达 15.4%的功率转换效率。
