We report four new iridium(III) complexes of the type [Ir(ppy) 2(N^N)][PF6] in which N^N is a 4,6-diphenyl-2,2'- bipyridine and the 4-phenyl ring is substituted at either the para or meta positions [4-Me, N^N = 1; 4-Br, N^N = 2; 3,5-Br2, N^N = 3; 3,5-(C6H4-4-NPh2)2, N^N = 4]. The complexes have been fully characterized, and single-crystal diffraction analyses of [Ir(ppy)2(N^N)][PF6] (N^N = 1-3) confirmed that each [Ir(ppy)2(N^N)]+ cation exhibits face-to-face π-stacking between the pendant phenyl substituent of the N^N ligand and the cyclometallated phenyl ring of an adjacent [ppy]- ligand. In solution, the complexes are short-lived emitters; the emission maxima for [Ir(ppy)2(1)][PF6], [Ir(ppy)2(2)][PF 6], and [Ir(ppy)2(4)][PF6] are similar (λem = 600-608 nm), but the presence of the two bromo substituents in [Ir(ppy)2(3)][PF6] produces a redshift of ca. 30 nm. The solid-state photoluminescent emission spectra of thin films of the complexes are similar to those in solution. The performances of the complexes as electroluminescent components in light-emitting electrochemical cells (LECs) have been evaluated. The electroluminescence spectra show slight blueshifts with repect to the photoluminscence bands. LEC turn-on times vary from instantaneous for N^N = 2 to 2 h for N^N = 1. The device data suggest that the incorporation of Br substituents into the N^N co-ligand may not be beneficial. Four [Ir(ppy)2(N^N)][PF6] (N^N = 4,6-diphenyl-2,2'-bipyridine derivative) complexes have been synthesized and characterized. In solution, the complexes are short-lived emitters with emission maxima between 600 and 635 nm; the solid-state emission spectra are similar. The performances of the complexes as electroluminescent components in LECs have been evaluated. Copyright

Five substituted-2,2′-bipyridine ligands L, (4-(p-methylphenyl)-6-phenyl-2,2′-bipyridine (L1), 4-(p-bromophenyl)-6-(p-bromophenyl)-2,2′-bipyridine (L2), 4-(p-bromophenyl)-6-phenyl-2,2′-bipyridine (L3), 4-phenyl-6-(p-bromophenyl)-2,2′-bipyridine (L4), and 4-(p-fluorophenyl)-6-(p-fluorophenyl)-2,2′-bipyridine (L5) were synthesized by stepwise formation. Reaction of cis-[RuCl2(bpy)2]2H2O or cis-[RuCl2(phen)2]2H2O and the substituted-2,2′-bipyridine ligands in the presence of KPF6 afforded the corresponding cationic polypyridine-ruthenium complexes of the type [(bpy)2Ru(L)](PF6)2 (bpy = 2,2′-bipyridine, 1-5) or [(phen)2Ru(L)](PF6)2 (phen = 1,10-phenanthroline, 6-10), respectively. All complexes have been spectroscopically characterized by UV-vis, luminescence, and electrogenerated chemiluminescence. The structures of 1CH3COCH3, 3CH3COCH3, 52CH3COCH3, 6, 8, 9, and 10 have been determined by single-crystal X-ray diffraction.
