Abstract: Five heteroleptic, cyclometalated (C$$^{\wedge }$$∧N) Iridium(III) complexes of acetylacetone (acac) and 1-phenyl-isoquinoline (piq) derivatives, Ir(acac)(piq)$$_{2}$$2, Ir(acac)(2,4-difluoro-piq)$$_{2}$$2, Ir(acac)(4-trifluoromethyl-piq)$$_{2}$$2, Ir(acac)(4-N,N-dimethyl-piq)$$_{2}$$2, Ir(acac)(4-acetyl-piq)$$_{2}$$2, were synthesized and characterized. The ($$\text {C}^{{\wedge }}\text {N})_{2}$$C∧N)2Ir(acac) complexes in toluene showed phosphorescence ($$\uplambda _{\max… read more here.

Abstract: Three ruthenium complexes containing a bidentate piq ligand, [(piq)Ru(bpy)2]2+ (1), [(piq)Ru(phen)2]2+ (2), and [(piq)Ru(DIP)2]2+ (3) (piq = phenylisoquinolinate, bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, DIP = 4,7-diphenyl-1,10-phenanthroline), were prepared. The DNA binding properties of complexes 1-3 to double-stranded DNA were studied. The binding… read more here.
