respectively. Four trinuclear complexes [(bpy)6Ru3L1–4](PF6)6 (Ru-L1–4) were obtained by reaction of Ru(bpy)2Cl2·2H2O with ligands L1–4. The photophysical behaviors of these complexes were investigated by UV/Vis absorption and emission spectrometry. The complexes display metal-to-ligand charge transfer absorptions at 441–445 nm and emissions at 571–578 nm. Cyclic voltammetry data of the complexes show one RuII-centered
合成了四个源自 4,5-二氮杂芴-9-one 的三足配体 L1-4。L1-2 分别由 4,5-二氮杂芴-9-肟与 1,3,5-三(溴甲基)苯和 1,1,1-三(对甲苯磺酰氧基甲基)丙烷和 L3-4 反应形成由 9-(4-羟基) 苯基亚氨基-4,5-二氮杂芴分别与 1,3,5-三(溴甲基)苯和 1,1,1-三(对甲苯磺酰氧基甲基)丙烷缩合形成。四种三核配合物 [(bpy)6Ru3L1-4](PF6)6 (Ru-L1-4) 通过 Ru(bpy)2Cl2·2H2O 与配体 L1-4 的反应获得。通过紫外/可见光吸收和发射光谱法研究了这些配合物的光物理行为。这些配合物在 441-445 nm 处显示出金属到配体的电荷转移吸收,在 571-578 nm 处显示出发射。
