Abstract

original image

Wire self-assembly: Short oligo(phenylene ethynylene) modules (black structures, see picture) are assembled by attached DNA strands, which also direct the formation of 1,3-diyne linkages between the modules by the Cu-mediated Glaser–Eglinton reaction to selectively form dimer, trimer, and tetramer conjugated wires of up to 8 nm in length.
