Reference of 15746-57-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II). In a document type is Article, introducing its new discovery.
The preparation and photophysical characterization of a of redox-active lysines and related model compounds based on polypyridyl ruthenium complexes are described. Donor-chromophore-acceptor triad 1, [PTZpn-Lys(RuIIb2m)2+-NH-prPQ2+] (PF6-)4 (see below), by of a bipyridyl caromophore (RuIIb2m, where b = 2,2?-bipyridine, m = 4?-methyl-2,2?-bipyridyl-4?-carbonyl), an electron donor (phenothiazine, PTZ), and an (paraquat, PQ2+) on a (Lys) scaffold utilizing bonds. This derivatized amiono acid exihibited efficient (>95%) quenching of the ruthenium metal-to-ligand charge-transfer (MLCT) excited state upon irradiation with a 420-nm laser pulse in CH3CN. The resulting state, [(PTZpn+)-Lys(RuIIb2m) 2+-NH-(prPQ+)]) 1.17 eV and lived for 108 ns (k = 9.26 × 106 s-1) as observed by transient absorption spectrosoopy. Also studied was a of related model systems that included model chroaophores, simple chromophore-quencher dyads linked by amide bonds, and chromophore-queneher dyads on lysine. An account of the of kinetic behavior of these system including triad 1 and a discussion of factors that influence the lifetime of the redox-separated states, their efficiency of formation, their energy storage ability are presented.
