Cyclodextrin recognition sites are assembled in macromolecular structures by using metal assembly principles. Methylated cyclodextrins are functionalised with bidentate bipyridine and tridentate terpyridine units to give versatile receptor ligands, β‐CD−mbpy and β‐CD−ttp, respectively, for metal complexation. Tris‐cyclodextrin complexes are prepared by reaction of the β‐CD−mbpy receptor with iron(II) and by reaction of β‐CD−ttp with europium(III). The latter leads to a luminescent complex with three recognition sites around the luminescent metal core. Bis‐cyclodextrin complexes are prepared by addition of iron(II) to β‐CD−ttp. The characterisation of the compounds and their luminescent properties are reported.
