dc.descriptionA macrocyclic compound consisting of six anthracene units formed a Saturn-shaped complex with fullerene C70as the ellipsoidal guest. The association constant of the host-guest complex was determined by the NMR titration method to be 4.6 © 103L mol11, twice than observed for the C60counterpart. X-ray analysis revealed that the guest molecule was included in the center of the cavity in nearly standing orientation, whereas DFT calculations predicted the complexation in various orientations. In any complex structure, CH£π interactions play an important role in forming the ringbody supramolecular system. The intraannular hydrogen atoms in the ring moiety were deshielded upon complexation, and this phenomenon is discussed on the basis of the NMR shielding of C70and the calculated structures. In spite of the different relative orientations of C70, the host-guest formation strength remains similar exposing the great versatility of the host capabilities against non-spherical fullerenes. © 2019 The Chemical Society of Japan.
