2,2':6',2''-Terpyridine meets 2,6-bis(1H-1,2,3-triazol-4-yl)pyridine: tuning the electro-optical properties of ruthenium(II) complexes.

The synthesis of a series of heteroleptic ruthenium(ii)-complexes containing both, 2,2':6',2''-terpyridine and 2,6-bis(1H-1,2,3-triazol-4-yl)pyridine, is reported for the first time. The provided complexes feature photophysical and electrochemical properties in between those known for the respective homoleptic complexes. The flexibility with respect to lateral functional groups to be introduced into the complexes underlines the high potential for further functionalization steps.
