- Abstract:
- Pyridine-based ligands, such as 2,20-bipyridine and 1,10-phenanthroline, have gained much interest in
the fields of supramolecular chemistry as well as materials science. The appealing optoelectronic
properties of their complexes with heavy d6 transition metal ions, such as Ru(II), Os(II), Re(I) and Ir(III),
primarily based on the metal-to-ligand charge-transfer (MLCT) nature featuring access to chargeseparated
states, have provided the starting point for many studies in the field of dye-sensitized solar
cells (DSSCs), organic light emitting diodes (OLEDs), artificial photosynthesis and photogenerated
electron as well as energy transfer processes. This critical review provides a comprehensive survey over
central advances in the field of soluble metal-containing macromolecules in the last few decades. The
synthesis and properties of functionalized 2,20-bipyridyine- and 1,10-phenanthroline-based d6 metal
complexes, in particular, their introduction into different prevailing polymeric structures are highlighted.
In the most part of the review metal complexes which have been attached as pendant groups on the
polymer side chain are covered. Selected applications of the herein discussed metal-containing
macromolecules are addressed, particularly, with respect to photogenerated electron/energy transfer
processes. In order to enable a deeper understanding of the properties of the ligands and metal
complexes, the fundamentals of selected photophysical processes will be discussed (223 references).
