摘要
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).
