Halogenverbrückte supramolekulare Kapseln im Festkörper, in Lösung und in der Gasphase

Abstract: Supramolekulare Kapseln wurden durchn eutrale Halogenbrücken (XBs) aufgebaut und im Festkçrper,i n Lçsung sowie in der Gasphase untersucht. Die Geometrie der hoch organisierten Kapseln wird durch eine Rçntgenkristallstruktur belegt, die den Aufbau aus zwei XB-Hemisphären zeigt, die geometrischd urchH -Brücken zu achtM eOH-Molekülen verfestigt sind und zwei Benzol-Gäste einschließen. Aufgrund von Desolvatationseffekten in protischen Lçsungsmitteln führen ¾nderungen des XB-Donors zu einer effektiveren Erhçhung d… Show more

“…The report paves the way for halonium-ionbased nanotechnology to be used for constructing structurally precise and robust gigantic nanomolecules. mass spectrometry (ESI-MS) [17][18][19][20][21][22] can provide an unambiguous structure assignment, including information on chemical composition, size, and binding mode of the capsules. Carefully done diffusion NMR studies in non-polar solvents such as chloroform and benzene have shown that no specific guest or template molecules are needed in the self-assembly of hexameric capsules from resorcinarenes 23 and pyrogallarenes.…”

“…Weiterhin erwies sich die Optimierung des XB-Donors innerhalb neutraler Systeme als effizienter als die Optimierung des entsprechenden Akzeptors. [49] Dies stellt somit eine weitere Designregel zur systematischen Optimierung neuer Rezeptoren dar.…”
