Abstract
A cross-bred organic semiconductor (OSC) polymer, includes a diketopyrrolopyrrole (DPP)-fused thiophene polymeric material, such that: the DPP-fused thiophene polymeric material comprises a first linear alkyl-substituted DPP portion and a second branched alkyl-substituted DPP portion, the cross-bred OSC polymer comprises a repeat unit having both the first linear alkyl-substituted DPP portion and the second branched alkyl-substituted DPP portion, and the fused thiophene is beta-substituted.
Claims6
A polymer blend, comprising:
- at least one cross-bred organic semiconductor (OSC) polymer and at least one crosslinker,
