A new DNA‐mimetic π‐conjugated polymer poly(triphenylamine‐carbazole) (PTC‐U) has been prepared which exhibits high thermal stability, non‐corrosion, excellent hole injection and electron‐blocking abilities in the solid state owing to the uracil induced physical cross‐linking. In addition, a trilayer device with PTC‐U as a hole injection/transport layer is approximately 1.6 times higher than that of the commercial product PEDOT:PSS‐based devices.
