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 i nterplay between the sequences allows one to generate a variety of structur es with well-defined shapes. We present a straightforward approach to gener ate self-organized organic semiconducting nanostructures. This approach is based on the spontaneous molecular organization of block copolymers contain ing one fully conjugated segment associated with a nonconjugated sequence. Such systems show high local contrast in their properties and are of intere st for applications in nanoscale patterning for quantum confinement of ligh t emission or fabrication of nanowire networks.
