- Abstract:
- The need for novel materials with luminescent properties and advanced processing features
requires reliable and reproducible synthetic routes for the design of suitable materials, such as e.g.
polypyridyl ruthenium(II) and iridium(III)-containing polymers. The most popular ligand for
those purposes is the 4,49-functionalized bipyridine unit. Therefore, several synthetic strategies for
the derivatization of the 4,49-dimethyl-2,29-bipyridine are highlighted, and in particular
functionalities, which enable further covalent linkage to polymeric structures, are discussed in this
critical review. Subsequently, the different synthetic strategies for the preparation of polymeric
metal-complexes are described, either starting from small functionalized complexes (later
covalently attached to the polymer), or from macroligands (subsequently coordinated to the metal
ions). The designed materials reveal good processing properties using spin coating and inkjet
printing, as well as beneficial electro-optical properties for potential thin functional film
applications, such as light-emitting electrochemical cells.
