Abstract The preparation of n‐type conjugated polymers (CPs) with low‐lying lowest unoccupied molecular orbital (LUMO) energy levels is crucial for developing organic electronics. However, limited strategies have been demonstrated to significantly lower the LUMO CPs. Herein, BDOPV incorporated strong electron affinity as acceptor unit and F‐substituted thiophene derivatives 4F2T 4FTVT donor into polymer chain, two CPs PB4F2T PB4FTVT are synthesized via an atom‐economic direct arylation monomer‐aldol polycondensation procedure. display below −4.0 eV enable unipolar charge transport characteristics in thin‐film transistors (OTFTs) facilitate efficient n‐doping by N ‐DMBI thermoelectric devices (OTEs). OTEs fabricated using enhanced performance, a conductivity (σ) 0.90 S cm⁻¹ power factor (PF) reaching up 0.50 µW m⁻¹ K⁻ 2 . This work enriches pool semiconductors combining withdrawing fluorinated comonomer effective synthetic protocol.
