Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Inorganic Chemistry called Electron Donor-Acceptor Dyads Based on Ruthenium(II) Bipyridine and Terpyridine Complexes Bound to Naphthalenediimide, Author is Johansson, Olof; Borgstroem, Magnus; Lomoth, Reiner; Palmblad, Magnus; Bergquist, Jonas; Hammarstroem, Leif; Sun, Licheng; Kermark, Bjoern, which mentions a compound: 89972-77-0, SMILESS is CC1=CC=C(C2=CC(C3=NC=CC=C3)=NC(C4=NC=CC=C4)=C2)C=C1, Molecular C22H17N3, HPLC of Formula: 89972-77-0.
Two series of photosensitizer-electron acceptor complexes were synthesized and fully characterized: ruthenium(II) tris(bipyridine) {[RuII(bpy)2(bpy-X-NDI)], where X = -CH2-, tolylene, or phenylene, bpy is 2,2′-bipyridine, and NDI is naphthalenediimide} and ruthenium(II) bis(terpyridine) {[RuII(Y-tpy)(tpy-X-NDI)], where Y = H or tolyl and X = tolylene or phenylene, and tpy = 2,2′:6′,2”-terpyridine}. The complexes were studied by cyclic and differential pulse voltammetry and by steady state and time-resolved absorption and emission techniques. Rates for forward and backward electron transfer were investigated, following photoexcitation of the ruthenium(II) polypyridine moiety. The terpyridine complexes were only marginally affected by the linked diimide unit, and no electron transfer was observed In the bipyridine complexes the authors achieved efficient charge separation For the complexes containing a Ph link between the ruthenium(II) and diimide moieties, the results suggest a biphasic forward electron-transfer reaction, in which 20% of the charge-separated state was formed via population of the naphthalenediimide triplet state.
In addition to the literature in the link below, there is a lot of literature about this compound(4-(p-Tolyl)-2,2:6,2-terpyridine)HPLC of Formula: 89972-77-0, illustrating the importance and wide applicability of this compound(89972-77-0).
