Nanodonuts form from hierarchical self‐organization of a melamine featuring π‐conjugated oligo(para‐phenyleneethynylene)s with a cyanurate. The toroidal nanostructures, with a diameter of 40 nm (see AFM image), form in decane under dilute conditions. S. Yagai, A. Ajayaghosh et al. propose in their Communication on page 4691 ff . that a hydrogen‐bonded rosette is an essential intermediate supramolecular species for such a hierarchical self‐organization process. The background picture shows a “bubble ring” made by a scuba diver.
