Artificial cylindrical and tubular aggregates of specifically programmed molecules are of interest as sensing, transport, and bioactive systems. An important design to form these aggregates is via ring stacking and most of these stacks are composed of single-molecule rings, for example, cyclic oligopeptides. [1] Hydrogen-bond interactions between molecules are attractive candidates for obtaining well-defined supramolecular cyclic structures due to their spatial arrangement and directionality. [2] Multiple examples of these cyclic structures exist that are based on hydrogen-bonding building blocks. [3] Further aggregation of cyclic supramolecular structures into extended aggregates is, however, scarce. [4] Recently, Stupp and co-workers described an elegant example of the self-assembly of dendron rod-coil molecules into tetrameric hydrogen-bonded rosettes that further organize into nanoribbons by additional hydrogen bonding and p--p interactions. [5] Nanohelices of cadmium sulfide were made by the mineralization of these aggregates. Fenniri et al. demonstrated the formation of rosette nanotubes in which the helicity could be tuned by using amino acids. [6] We and others have used noncovalent interactions to design p-conjugated oligomers that organize hierarchically over several length scales. [7] Self-assembled supramolecular structures of conjugated molecular building blocks are a
