Novel electron‐conducting block copolymers of styrene and perylene bisimide acrylate (PS‐ b ‐PPerAcr) self‐assemble into lamellar and cylindrical morphologies. It is shown that the dilution of n‐type chromophores with polystyrene in PS‐ b ‐PPerAcr does not reduce the charge‐carrier mobility compared to the corresponding homopolymer, which is attributed to the confinement of perylene bisimides in block copolymer domains.
