Several new TEMPO (2,2,6,6-tetramethylpiperidine N-oxide)-labeled ruthenium complexes were prepared. They can be discerned in two different classes featuring rigid and flexible linkers between the ruthenium(II)-polypyridyl complex and the stable nitroxide. The bis(heteroleptic) ruthenium complexes were synthesized from [Ru(L2)]Cl2 (L = 2,2'-bipyridine or 1,10-phenanthroline) and newly prepared phenanthroline-TEMPO-ligands. Finally, a tris(heteroleptic), spin-labeled ruthenium complex has been prepared from [Ru(DMSO)4]Cl2, dipyrido[3,2-a:2',3'-c]phenazine (dppz), 1,10-phenanthroline and a phenanthroline-TEMPO-ligand with a rigid linker.

The controlled incorporation of phenanthroline moieties into polymers is introduced, demonstrating their application as metal-ion complexing ligands for the construction of advanced macromolecular structures. Specifically, two phenanthroline-containing monomers based on acrylate and styrene functionalities, were synthesized. Each monomer was readily copolymerized with either N,N-dimethylacrylamide or styrene via nitroxide-mediated polymerization, resulting in narrowly distributed polar or non-polar copolymers. To demonstrate the versatility of the established polymer systems, the polar polymer was employed for transition metal induced single-chain nanoparticle formation, verified by diffusion-ordered NMR and UV/Vis spectroscopy. Furthermore, the non-polar polymer allows facile incorporation of lanthanide ions, creating luminescent metallo-polymers, in-depth characterized by advanced photophysical experiments and 2D NMR measurements.
