Supramolecular bidentate phosphine ligand scaffolds from deconstructed Hamilton receptors.

There is constant demand for new ligand archictectures on which inorganic and organometallic structures can be leveraged. An important, but often synthetically challenging, class of ligands is bidentate phosphines. Here we report self-assembling, supramolecular bidentate ligand scaffolds based on deconstructed Hamilton receptors with binding affinities up to 800 ± 100 M-1.
