Vaduvescu, Simona; Potvin, Pierre G. published an article about the compound: 4-(p-Tolyl)-2,2:6,2-terpyridine( cas:89972-77-0,SMILESS:CC1=CC=C(C2=CC(C3=NC=CC=C3)=NC(C4=NC=CC=C4)=C2)C=C1 ).Reference of 4-(p-Tolyl)-2,2:6,2-terpyridine. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:89972-77-0) through the article.
Four ditopic bridging ligands, containing 2,2′:6′,2”-terpyridine and 2,6-dipyrazinylpyridine (dpp) metal-binding units attached through p- or m-phenylene linkages, were incorporated into eight mono-, di- and trinuclear linear Ru(II) complexes. These were characterized by UV/visible spectroscopy and cyclic voltammetry, and by their ability to undergo light-induced electron transfers to methylviologen. The dpp-bearing complexes were more difficult to prepare but were superior sensitizers, a fact attributable to longer excited state lifetimes and an electrostatically favored reductive quenching pathway.
As far as I know, this compound(89972-77-0)Reference of 4-(p-Tolyl)-2,2:6,2-terpyridine can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
