An aryl-bridged dixanthene scaffold for building multinucleating ligands and supramolecular assemblies: Syntheses and structures

An aryl-bridged dixanthene scaffold is quickly prepared and readily derivatized with functional groups at the four 4,5-positions adjacent to the oxygen atoms of the two xanthene groups: syntheses of five potentially tetradentate, multinucleating, metal-binding ligands illustrate the usefulness of the methodology.
