WebIn this work, a new series of DPP-based n-type polymers have been developed by incorporating fused bithiophene imide oligomers (BTIn) into DPP polymers. The resulting copolymers BTIn-DPP show narrow band gaps as low as 1.27 eV and gradually down-shifted frontier molecular orbital energy levels upon the increment of imide group number. WebAmong various electron-deficient building blocks, bithiophene imide (BTI), as an imide-functionalized arene, has been proved as a prominent one for constructing n-type polymer semiconductors. 6 The β-positions of thiophenes in BTI afford an unprecedented opportunity for structural optimization via backbone expansion and core modification.
