LIGAND SUBSTITUTION PATTERNS CONTROL PHOTOPHYSICAL PROPERTIES OF RUTHENIUM(II)-2,2',/6',2''-TERPYRIDINE COMPLEXES - ROOM-TEMPERATURE EMISSION FROM [RU(TPY)2]2+ ANALOGS

Ruthenium(II) complexes of 2,2' : 6',2"-terpyridine have not been widely investigated as photocatalysts; the introduction of electron-withdrawing substituents into the 4'-position of the ligand results in complexes [Ru(Xtpy)2]2+ (Xtpy = Cltpy or MeSO2tpy), which luminesce in fluid solution at room temperature.
