Electron-Conducting Block Copolymers: Morphological, Optical, and Electronic Properties

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...

Zusammenfassung: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.
