Photochemical ligand ejection from non-sterically promoted Ru(ii)bis(diimine) 4,4′-bi-1,2,3-triazolyl complexes [PDF]

, 2014
Complexes of the form [Ru(diimine)2(btz)]2+ (btz = 1,1′-dibenzyl-4,4′-bi-1,2,3-triazolyl) are observed to undergo photochemical ejection of the btz ligand in the absence of any promotion through steric congestion to generate cis-bis(solvent) complexes ...

Complexes of ruthenium(II) and ruthenium(III) with tertiary arsines [PDF]

Journal of Inorganic and Nuclear Chemistry, 1977
Abstract Ruthenium trichloride reacts with stoichiometric amounts of tertiary arsines in boiling ethanol to give paramagnetic complexes, RuCl 3 (Ph 2 RAs) 3 (R = Me, Et, Pr, Bu), which react further with 2,2′-bipyridyl(bipy) and o -phenanthroline(phen) to yield brick red crystalline products, RuCl 3 (N-N)(Ph 2 RAs) (N-N = bipy, phen).

Synthetic Route of Trithiolato-Bridged Dinuclear Arene Ruthenium(II) Complexes [(η6-P-MeC6H4Pri)2Ru2(μ2-SR)3]+ [PDF]

, 2020
Several dinuclear thiophenolato-bridged arene ruthenium complexes [(η6-p-MeC6H4Pri)2Ru2(μ2-SC6H4-R)3]+ could so far onlybe obtained with moderate yields using the synthetic route established in the early 2000s.

Recent Investigations on Thiocyanate-Free Ruthenium(II) 2,2′-Bipyridyl Complexes for Dye-Sensitized Solar Cells

Molecules, 2021
Three decades ago, dye-sensitized solar cells (DSSCs) emerged as a method for harnessing the energy of the sun and for converting it into electricity. Since then, a lot of work has been devoted to create better global photovoltaic efficiencies and long ...

Metal complexes as DNA intercalators [PDF]

, 2011
DNA has a strong affinity for many heterocyclic aromatic dyes, such as acridine and its derivatives. Lerman in 1961 first proposed intercalation as the source of this affinity, and this mode of DNA binding has since attracted considerable research ...

Ruthenium porphyrin-ß-cyclodextrin complexes as supramolecular enzyme models for regioselective cleavage of carotenoids [PDF]

, 2006
All naturally occurring vitamin A derives from enzymatic oxidative cleavage of β,β-carotene or other carotenoids with pro-vitamin A activity. Two metabolic pathways of β,β-carotene to retinal (vitamin A aldehyde) have been proposed: the central cleavage ...
