摘要
合成了一种多联吡啶钌配合物(bpy)2Ru(phenCl4)(PF6)2,bpy为2,2′-联吡啶,phenCl4为3,4,7,8-四氯-1,10-邻菲罗啉,并用元素分析、红外光谱、核磁共振谱测试技术对结构进行了表征。化合物在紫外和可见光区均有吸收,在可见光区的最大吸收波长为440 nm,这是典型的金属到配体(MLCT)的跃迁,其光致发光性能也显示出MLCT迁移特征,并且随溶剂不同,其最大发射波长从630 nm变化至649 nm。配合物的电致化学发光性能受pH值影响不大,与随pH值增大电致化学发光强度增大的联吡啶钌不同,尤其在强碱条件下,其背景电致化学发光很小。
An o-phenanthroline-substituted ruthenium complex, [ Rubis （bipyridyl） （3,4,7,8-tetrachrolo-1, 10-phenanthroline） ] （PF6 ）2, was synthesized and the structure of the complex was characterized by elemental analysis, IR spectroscopy and ^1H NMR spectroscopy. The complex displayed absorption in the UV and visible regions, with a visible maximum absorption at 440 nm, a typical metal-to-ligand charge transfer （MLCT） transition. Photoluminescence emission also had the characteristics of MLCT transitions with the maxima wavelengths ranged from 630 to 649 nm depending on the solvent. The electrochemiluminescence （ECL） of the complex was found to be less dependant on pH, which was distinctly different from that of the well known ruthenium tris（bipyridine） complex. Furthermore the background ECL signal of the complex did not increase even under a strong alkaline condition.
