title: The Hairpin Furans: Easily Prepared Hybrids of Helicenes and Twisted Acenes.
abstract: The thermal reaction of a cyclopentadienone with 6,6'-dimethoxy-5,5'-binaphthoquinone gives, in a single step, a molecular ribbon consisting of two twisted aromatic systems fused to a heteropentahelicene. Such molecules constitute a new class of chiral polycyclic aromatic compounds, the "hairpin furans".
