A number of metallohosts mimicking dinuclear copper oxygenases have been designed and synthesized. These metallohosts combine a substrate binding site, i.e. the diphenylglycoluril basket receptor, with two types of metal‐binding ligands, viz. tri‐coordinating bis(2‐ethylpyridine)amine (PY2) and tetra‐coordinating tris(2‐methylpyridine)amine (TPA). The preparation of the bis‐Cu I complexes of the ligand‐appended receptors and their characterization by NMR are reported. NMR spectroscopic data provide evidence for a dynamic inclusion behavior of some of the pyridine moieties in the receptor of both the metal‐free ligands and the Cu I complexes.
