Using a “multifluorination” strategy , ambipolar donor–acceptor conjugated polymer with hole and electron mobility (μ h and μ e ) up to 3.94 and 3.50 cm 2 V −1 s −1 , respectively, and unipolar n‐type donor–acceptor conjugated polymers with μ e up to 4.97 cm 2 V −1 s −1 is synthesized with isoindigo as acceptor units.
