Preparation of a supramolecular heterocyclic host complex using chiral (1R,2S)-2-amino-1,2-diphenylethanol

Three types of supramolecular heterocyclic host complexes were successfully prepared using chiral (1R,2S)-2-amino-1,2-diphenylethanol and three basic types of heterocyclic (thiophene, furan, and pyrrole) acid derivatives. These host complexes are composed of a chiral 21-helical columnar network structure. It also contains channel-like cavities formed by the assembly of these chiral 21-helical columns, which include guest alcohol molecules.

► Supramolecular chiral heterocyclic (thiophene, furan, and pyrrole) hosts were prepared.
► These chiral hosts have channel-like cavities which can include guest alcohol molecules.
► The inclusion host composed of the thiophene ring showed solid-state fluorescence.
► The behavior of discharge of guests was different according to the kind of heterocyclic ring.
