Syntheses, crystal structures, photophysics and cation-binding studies of luminescent functionalized ruthenium polypyridine complexes with orthometallated aminocarbene ligands

A series of luminescent functionalized ruthenium polypyridine complexes with orthometallated aminocarbene ligands has been synthesized and their photophysical properties studied. The cation-binding properties of one crown-ether functionalized complexes have also been studied. The X-ray crystal structures of [ Ru(bpy)2C(CH2-B15C5)NHC 6H3Br]OTf and [ Ru(5,5-Me2bpy)2=C(CH2Ph)NHC 6H3Br]OTf have been determined (bpy = 2,2ʹ-bipyridine; 5,5ʹ-Me2bpy = 5,5ʹ-dimethyl-2,2ʹ-bipyridine; B15C5 = benzo-15-crown-5).
