Photoinduced ligand isomerisation in a pyrazine-containing ruthenium polypyridyl complex.
Photochemically-induced ligand rearrangements for the N2 and N4 coordination isomers of the complex [Ru(bpy)(2)(Hpztr)](2+) and its deprotonated analogue [Ru(bpy)(2)(pztr)](+), where bpy is 2,2'-bipyridyl and Hpztr is pyrazine-1,2,4-triazole ligand, are reported. (1)H NMR spectroscopic and HPLC studies indicate that in acetone and acetonitrile the complexes are photostable when the triazole rin...
متن کاملInteraction of polypyridyl ruthenium (II) complex containing asymmetric ligand with DNA.
A novel asymmetric bidentate ruthenium (II) complex, [Ru(bpy)(2)(PYNI)](2+) (bpy=2,2'-bipyridine, PYNI=2-(2'-pyridyl)naphthoimidazole), has been synthesized and characterized by elemental analysis, ES-MS (electrospray mass spectra) and (1)H NMR. The electrochemical behaviors of this complex were studied by cyclic voltammetry. DNA interaction studies suggest that [Ru(bpy)(2)(PYNI)](2+) binds to ...
متن کاملThiocyanate linkage isomerism in a ruthenium polypyridyl complex.
Ruthenium polypyridyl complexes have seen extensive use in solar energy applications. One of the most efficient dye-sensitized solar cells produced to date employs the dye-sensitizer N719, a ruthenium polypyridyl thiocyanate complex. Thiocyanate complexes are typically present as an inseparable mixture of N-bound and S-bound linkage isomers. Here we report the synthesis of a new complex, [Ru(te...
متن کاملMechanism of cellular uptake of a ruthenium polypyridyl complex.
Transition metal complexes provide a promising avenue for the design of therapeutic and diagnostic agents, but the limited understanding of their cellular uptake is a roadblock to their effective application. Here, we examine the mechanism of cellular entry of a luminescent ruthenium(II) polypyridyl complex, Ru(DIP) 2dppz (2+) (where DIP = 4,7-diphenyl-1,10-phenanthroline and dppz = dipyridophe...
متن کاملSelf-assembled supramolecular cages containing ruthenium(II) polypyridyl complexes.
Substitution-inert, redox- and photo-active ruthenium(II) complexes based on 2,2',6',2''-terpyridine ligands were self-assembled into discrete supramolecular cages via coordination to palladium(II) centres and characterised by NMR, ESI-MS and X-ray crystallography.
