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+.
Key words: Ru(II) complex, electrochemiluminescence, bipyridine, phenanthroline
