para‐Connected Cyclophenylenes and Hemispherical Polyarenes: Building Blocks for Single‐Walled Carbon Nanotubes?

Carbon nanotubes by design? Cyclo-para-phenylenes are monomers for the synthesis of armchair carbon nanotubes (see picture, right), and are also attractive fluorophores that display size-dependent emission properties. Geodesic polyarenes represent a realistic alternative for the rational design of carbon nanotubes through the chemical elongation of the hydrocarbon template (left).
