A bis‐diketopyrrolopyrrole (DPP dimer, 2DPP) core is synthesized with much stronger electron deficiency than DPP by homocoupling of DPP. 2DPP‐based polymers, P2DPP‐BT, P2DPP‐TT, P2DPP‐TVT, and P2DPP‐BDT, are obtained. Top‐gated organic field‐effect transistors on plastic substrate are fabricated. Compared with their mono‐DPP‐based polymers, remarkable improvement of electron mobilities of P2DPPs is achieved. Meanwhile, their p‐channel performance becomes higher.
