We report a step-saving new access to D–p–D–p–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%.
