Benzobis(imidazolium) salts ([BBI-H2-R4]2+, R = alkyl, aryl) interact with crown ethers through a combination of hydrogen bonds, ion-dipole, and π-π stacking interactions to form starburst [24]pseudo-rotaxanes. This new recognition motif allows the extension of four side-arms directly from the cavity of the crown ether, thus positioning the wheel component in a straddled orientation onto the axle, while their carbene-based derivatives show the classical shape of regular [22]pseudorotaxanes.
