A novel method for the synthesis of a thiophene analogue of isoindigo (TIIG) is described. The reaction involves a palladium‐catalyzed C–H activation/oxidative cyclization sequence. This new methodology has potential for diversifying the isoindigo family. The thin‐film transistors (TFTs) prepared from a TIIG‐based copolymer (PIDTT‐TIIG) with indacenodithieno[3,2‐ b ]thiophene (IDTT) exhibit unipolar charge‐transport properties with hole mobilities of 0.17 cm 2 V –1 s –1 .
