Abstract

Highly twisted permethoxylated hexa‐peri‐hexabenzocoronene forms inclusion complexes with hexafluorobenzene and fullerene guest molecules. In addition to the “double‐concave” surface which allows its coordination to suitable guest molecules on both sides, the flexible methoxy groups at the periphery of this host molecule adjust their orientation to the size and shape of the guest molecules. Further details are reported in the Communication by K. Müllen et al. on page 1247 ff.
