Electron-conducting block copolymers:: Morphological, optical, and electronic properties

Novel electron-conducting block copolymers of styrene and perylene bismide 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 bismides in block copolymer domains.
