The heteroleptic complexes [Ru(1)(4)][PF6]2, [Ru(2)(4)][PF6]2, [Ru(Phtpy)(4)][PF6]2, and [Ru(pytpy)(4)][PF6]2 (Phtpy = 4′-phenyl-2,2′:6′,2″-terpyridine, pytpy = 4′-(4-pyridyl)-2,2′:6′,2″-terpyridine, 1 and 2 = 4-methyl ester substituted derivatives of Phtpy and pytpy, 4 = ethyl 2,2′:6′,2″-terpyridine-4′-phosphonate) have been prepared. The single crystal structure of ligand 1 (1 = methyl 4-carboxy-4′-phenyl-2
杂配配合物 [Ru(1)(4)][PF6]2、[Ru(2)(4)][PF6]2、[Ru(Phtpy)(4)][PF6]2 和 [Ru(pytpy) )(4)][PF6]2 (Phtpy = 4'-phenyl-2,2':6',2"-terpyridine, pytpy = 4'-(4-pyridyl)-2,2':6',2已经制备了“-三联吡啶,1和2=Phtpy和pytpy的4-甲基酯取代衍生物,4=2,2':6',2”-三联吡啶-4'-膦酸乙酯)。报道了配体 1 (1 = 甲基 4-羧基-4'-苯基-2,2':6',2"-三联吡啶)的单晶结构。4-甲基酯基团的引入导致钌 (II) 配合物的 MLCT 带发生小红移,并导致 Ru2+/Ru3+ 对向更正电位的小移。新配合物应作为开发适用于 p 型半导体敏化的钌 (II) 染料的有用起点。
