Organized semiconducting nanostructures from conjugated block copolymer self-assembly

Self-assembly of block copolymers is attractive for nanodevice fabrication because the association of different polymers by covalent bonding and the interplay between the sequences allows one to generate a variety of structures with well-defined shapes. We present a straightforward approach to generate self-organized organic semiconducting nanostructures. This approach is based on the spontaneous molecular organization of block copolymers containing one fully conjugated segment associated with a nonconjugated sequence. Such systems show high local contrast in their properties and are of interest for applications in nanoscale patterning for quantum confinement of light emission or fabrication of nanowire networks.
