Supramolecular dye assemblies

For the most general approach to construct supramolecular dye assemblies through metal coordination, dye molecules must possess appropriate Lewis basic coordination sites, which are, however, usually scarce in parent dye molecules. Therefore, aromatic aza ligands, especially pyridyl, bipyridyl and terpyridyl groups, are often introduced into dye molecides by established organic synthetic routes to enable metal-aza Hgand interactions for the construction of dye assemblies of diverse structures and properties. Surprisingly, few classes of dyes have been subjected so far to produce supramolecular...
