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, Journal of the Chemical Society, Chemical Communications called Coordination chemistry at a surface: polymetallic complexes prepared on quartz by alternate deposition of iron(II) and ruthenium(II) centers, Author is Liang, Yongwu; Schmehl, Russell H., 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, SDS of cas: 89972-77-0.
Polymetallic complexes having well defined geometries were prepared via attachment of an anchor ligand to a quartz surface followed by repeated sequential reaction with [Fe(OH2)6]2+ and a RuII complex having two tridentate bridging ligands rigidly fixed at 180°, [(tpy-ph-tpy)2Ru]Cl2 [tpy-ph-tpy = 1,4-di(2,2′,6′,2”-terpyridin-4′-yl)benzene].
Although many compounds look similar to this compound(89972-77-0)SDS of cas: 89972-77-0, numerous studies have shown that this compound(SMILES:CC1=CC=C(C2=CC(C3=NC=CC=C3)=NC(C4=NC=CC=C4)=C2)C=C1), has unique advantages.
