Self‐organization on three length scales is exhibited by a block copolymer of styrene and an oligothiophene‐bearing isoprene in cast films. For example, a phase‐separated nanostructure consisting of π‐conjugated oligothiophene molecules is self‐aligned perpendicular to the substrate, as revealed in a TEM image of a section through the film (see picture).
