Abstract

Stripes on a plane: A set of highly ordered microscopic stripes (purple; see scheme) were produced over a large area by using controlled evaporative self-assembly in a cylinder-on-Si geometry of conjugated homopolymers or all-conjugated diblock copolymer (P3BHT). The crystallinity of the as-prepared assemblies of P3BHT was greatly improved following chloroform vapor annealing, resulting in a fourfold increase in electrical conductivity.
