- Abstract:
- The synthesis of a variety of 2-(1H-1,2,3-triazol-4-yl)-pyridines by click
chemistry is demonstrated to provide straightforward access to mono-functionalized
ligands. The ring-opening polymerization of e-caprolactone initiated by such a
mono-functionalized ligand highlights the synthetic potential of this class of bi-dentate ligands with respect to polymer chemistry or the attachment onto surfaces
and nanoparticles. The coordination to RuII ions results in homoleptic and heteroleptic
complexes with the resultant photophysical and electrochemical properties
strongly dependent on the number of these ligands attached to the RuII core.
