摘要：
The electrogenerated chemiluminescence (ECL) of Ru(dp-bpy)3(2+) (dp-bpy = 4,4'-diphenyl-2,2'-bipyridine) and Ru(dp-phen)3(2+) (dp-phen = 4,7-diphenyl-1,10-phenanthroline) in acetonitrile and aqueous solutions was studied. The diphenyl-substituted compounds produced a more intense emission than the nonsubstituted Ru(bpy)3(2+) in acetonitrile. The ECL efficiencies, phi(ECL), of Ru(dp-bpy)3(2+) and Ru(dp-phen)3(2+) were estimated as 14% and 24% respectively. Similar results were obtained in aqueous solutions.
