Modulation and binding properties of extended glycoluril molecular clips

• A glycoluril clip (1) provides a deep cavity for binding of guest molecules. Guest species interactpreferentially via hydrogen bonding or ion–lone pair interactions. Complexation-inducedconformational modulation of the cavity wall distance was observed. At higher guest–host ratios,inclusion compounds with organic guest molecules are obtained. The X-ray crystallographicstructure of 1.(NH4PF6).3CHCl3.2CH3OH shows formation of a network of clips connected viapolar and non-polar interactions.
