Self-Assembly of Trisoligonucleotidyls: The Case for Nano-Acetylene and Nano-Cyclobutadiene.

Rapid cooling is the recipe for the self-assembly of nanostructures from trisoligonucleotidyls, a novel class of branched oligonucleotides whose 3'-termini are connected by a trifunctional linker. The topology of the smallest complex is formally equivalent to the topology of acetylene, if a DNA double strand is envisioned as a C-C bond. The model of nano-acetylene is shown.
