Electrogenerated chemiluminescence: Part 54. Electrogenerated chemiluminescence of ruthenium(II) 4,4'-diphenyl-2,2'-bipyridine and ruthenium(II) 4,7-diphenyl-1,10-phenanthroline systems in aqueous and acetonitrile solutions
1991
Abstract The electrogenerated chemiluminescence (ECL) of Ru(dp-bpy) 2+ 3 (dp-bpy = 4,4'-diphenyl-2,2'-bipyridine) and RuCdp-phen) 2+ 3 (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) 2+ 3 in acetonitrile. The ECL efficiencies, o ECL , of Ru(dp-bpy) 2+ 3 and Rutdp-phen) 2+ 3 were estimated as 14% and 24% respectively. Similar results were obtained in aqueous solutions.
