A liquid-crystalline coordination compound immobilized on an oligomeric superstructure free from cross-linking (see Figure) is reported for the first time. A highly versatile synthetic methodology is described that allows unsymmetrical, mono-functionalized, metal-containing liquid-crystalline coordination complexes to be prepared. Related materials may find uses as novel catalysts.
