Two series of cyclometallated and noncyclometallated ruthenium(II) complexes incorporating mono- or disubstituted 1,10-phenanthroline- and 2,2′:6′,2′′-terpyridine-type ligands have been synthesized and characterized. An X-ray crystal structure for one of the complexes, Ru(ttpy)(mapH)-(Cl)(PF6), has been obtained (mapH = 2-p-anisyl-1,10-phenanthroline; ttpy = 4′-tolyl-2,2′:6′,2′′-terpyridine). Distinct
已经合成并表征了两个系列的环金属化和非环金属化钌 (II) 配合物,它们包含单取代或双取代的 1,10-菲咯啉和 2,2':6',2''-三联吡啶型配体。已获得其中一种配合物 Ru(ttpy)(mapH)-(Cl)(PF6) 的 X 射线晶体结构(mapH = 2-p-anisyl-1,10-phenanthroline;ttpy = 4'- tolyl-2,2':6',2''-三联吡啶)。已经观察到两个系列的不同电化学和光物理特性:一个显着的特征是观察到三个环金属化配合物的相对长寿命的 MLCT 激发态(室温下 CH3CN 中为 70 到 106 ns)。讨论了环金属化配体的σ捐赠等因素的作用,
