Molecular recognition directed self‐assembly of tubular supramolecular architectures from building blocks containing monodendrons as exo‐receptors and crown‐ or pseudo‐crown‐ethers as endo‐receptors

The principles of self‐assembly of tapered exo ‐receptors constructed from monodendrons containing crown‐ether, oligooxyethylenic groups and polymer backbones as endo ‐receptors into tubular supramolecular architectures are described with selected examples. In the case of polymers with flexible backbones it is suggested that a helical chain conformation is induced during the assembly of its own tapered side groups. This mechanism is supported by the enhanced self‐assembling ability of tapered side groups attached to a backbone with rigid helical conformation.
