Syntheses, characterization and third-order nonlinear optical properties of ruthenium(II) complexes containing 2-phenylimidazo-[4,5-f][1,10]phenanthroline and extended diimine ligands

Breaking the barrier: an osmium photosensitizer with unprecedented hypoxic phototoxicity for real world photodynamic therapy

“…Due to similarities between these spin systems, a appeared close to 2,9, and b appeared close to 3,8, and c appeared relatively close to 4,7. The signal for the imidazole-NH hydrogen was not observed, in agreement with the literature, 85,86,89 where quick exchange between the two nitrogens of the imidazole ring occurs in solution.…”

A Series of CuI Complexes Containing 1,10‐Phenanthroline Derivative Ligands: Synthesis, Characterization, Photophysical, and Oxygen‐Sensing Properties

“…2‐Phenyl‐1 H ‐imidazo[4,5‐ f ][1,10]phenanthroline (pip): The pip ligand was synthesized according to reported procedures 6c,6d…”

Synthesis, characterization and DNA binding studies of two mixed ligand complexes of ruthenium(II)

“…On the other hand there is a consensus about intercalative binding of complexes such as [Ru(bpy) 2 (dppz)] 2+ and [Ru(phen) 2 (dppz)] 2+ (dppz = dipyrido[3,2-a:2 0 ,3 0 -c]-phenazine). In these two complexes dppz ligand intercalates between the base pairs of double helical DNA [19][20][21][22][23][24]. Ever since the report of the DNA bases mismatch recognition agent, [Rh(bpy) 2 -(chrysi)] 3+ (chrysi = 5,6-chrysenequinone diimine), there has been renewed interest in the synthesis of mixed ligand complexes of transition metal ions.…”
