Self-organized semiconducting structures can be generated by including conjugated chains in block copolymers, it is reported here. Thin films of rod–coil copolymers containing a conjugated and a non-conjugated segment show nanoribbons of the conjugated material (see Figure), indicating that this approach may open the door to an easy method for nanowire fabrication.
