Racemic on the outside, but not inside: Aromatic‐foldamer hosts are enantiomers and as such prefer to co‐crystallize even though the guests (e.g. L‐tartaricacid, see picture) in each host are not present as enantiomers. This behavior allows a one‐step structure elucidation of diastereomeric and quasi‐racemic structures in the solid state.
