Halogen bonding has been used to glue together hydrogen‐bonded short arylamide foldamers to achieve new supramolecular double and quadruple helices in the solid state. Three compounds, which bear a pyridine at one end and either a CF2I or fluorinated iodobenzene group at the other end, engage in head‐to‐tail N⋅⋅⋅I halogen bonds to form one‐component supramolecular P and M helices, which stack to afford...
Ein Ring, sie zu binden: Die Bildung intramolekularer CH⋅⋅⋅O‐Wasserstoffbrücken wurde zur Herstellung neuer aromatischer Triazolfoldamere genutzt. Alle Triazoleinheiten dieser Foldamere zeigen nach innen und bilden so einen Stickstoffring. Damit können die Foldamere effizient neutrale zwei‐ und dreizähnige Organohalogenverbindungen durch mehrfache N⋅⋅⋅X‐Halogenbrücken (X=Cl, Br, I) binden, wobei stabile...
