Ruthenium(II) Metallo-Supramolecular Polymers of Click-Derived Tridentate Ditopic Ligands
New ditopic 2,6-bis(1,2,3-triazol-4-yl)pyridine ligands featuring a p-conjugated spacer and clicked-on solubilizing groups were employed in the synthesis of RuII metallo-supramolecular polymers that exhibit an intense metal-to-ligand charge transfer absorption in the visible light region. The coordination polymers obtained were studied in solution by means of size exclusion chromatography and analytical ultracentrifugation, revealing a comparably high molar mass and moderate rigidity. Investigations in the solid state by atomic force and transmission electron microscopy confirmed the formation of rod-like polymers. Furthermore, film preparation by drop-casting showed good film-forming properties. Thus, the solution-processable, photoredoxactive polymers might be applicable in solar cells.
