A new class of ambipolar donor‐acceptor π‐conjugated polymers based on a dithienocoronenediimide core is presented. Solution‐processed top‐gate/bottom‐contact thin film transistors (TFTs) exhibit electron and hole mobilities of up to 0.30 cm 2 /V·s and 0.04 cm 2 /V·s, respectively, which are the highest reported to date for an ambipolar polymer in ambient conditions. The polymers presented here are the first examples of coronenediimide‐based semiconductors showing high organic TFT performances.
