比较研究了以C2O42－为共反应物时5个结构相关的Ru(II)配合物[Ru(bpy)2L1]2＋, [Ru(bpy)2L2]2＋, [Ru(bpy)2L3]2＋, [Ru(phen)2L1]2＋和[Ru(phen)2L2]2＋(其中bpy＝2,2′-联吡啶, phen＝1,10-邻菲啰啉, L1＝4-羧基苯基咪唑[4,5-f][1,10]邻菲啰啉, L2＝3-羧基-4-羟基苯基咪唑[4,5-f][1,10]邻菲啰啉, L3＝3,4-二羟基苯基咪唑[4,5-f][1,10]邻菲啰啉)的电致化学发光(ECL)性质. 结果表明, 酚羟基的存在能有效地淬灭Ru(II)配合物[Ru(bpy)2L2]2＋, [Ru(bpy)2L3]2＋和[Ru(phen)2L2]2＋的ECL, 其它Ru(II)配合物的ECL量子效率与[Ru(bpy)3]2＋相差不大.

Electrochemiluminescent (ECL) properties of 5 structurally related Ru(II) complexes of [Ru(bpy)2L1]2＋, [Ru(bpy)2L2]2＋, [Ru(bpy)2L3]2＋, [Ru(phen)2L1]2＋and [Ru(phen)2L2]2＋(where bpy＝2,2′-bipyridine, phen＝1,10-phenanthroline, L1＝4-carboxylphenylimidado[4,5-f][1,10]phenanthroline, L2＝3-carboxyl-4-hydroxylphenylimidado[4,5-f][1,10]phenanthroline, and L3＝3,4-dihydroxyphenylimidado- [4,5-f][1,10]phenanthroline) have been studied in CH3CN/H2O (V/V, 1∶1) by using oxalate as coreactant. The results indicate that the presence of hydroxyl in [Ru(bpy)2L2]2＋, [Ru(bpy)2L3]2＋and [Ru(phen)2L2]2＋effectively quenches ECL, and the other complexes exhibit comparable ECL efficiencies to [Ru(bpy)3]2＋.
