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
我们报告了通过一锅式连续C–H(杂)芳基化反应,可以分步进行的D–π–D–π–D型低聚芳基的新步骤。通常,这些低聚物是通过需要预官能化步骤的Stille或Suzuki偶联反应制备的。容易合成的线性低聚物是在
钙钛矿型太阳能器件中作为有效的空穴传输剂制造的,具有高达15.4%的功率转换效率。
