    Notes: Crown[n]cavitands were synthesized by alkylation of tetrahydroxycavitands with polyethyleneglycol ditosylates. The bridging of two hydroxy groups at adjacent aromatic rings by a pentaethyleneglycol unit is favored over the bridging of two hydroxy groups at opposite aromatic rings. The presence of a sodium base enhances the formation of the 1,2-crown[n]cavitand and improves the yield. The combination of 1,2-crown[6]cavitands with calix[4]arenes or resorcin[4]arenes resulted in potential receptor molecules with large hydrophobic surfaces.

    The Modular Approach in Supramolecular Chemistry (1998)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 1998 (1998), S. 2689-2702

    Topics: Chemistry and Pharmacology
    Notes: This review describes covalent and non-covalent combinations of building blocks, e.g. calix[4]arenes, resorcin[4]arenes, cyclodextrins, porphyrins, and cyclotriveratrylenes, leading to well-defined large (receptor) molecules.
