A series of o-phenanthroline-substituted ruthenium(II) complexes containing 2,2'-dipyridyl, 2-(2-pyridyl)benzimidazole, 2-(2-pyridyl)-N-methylbenzimidazole, 4-carboxymethyl-4'-methyl-2,2'-dipyridyl, and/or 4,4'-dimethyl-2,2'-dipyridyl ligands were synthesized and examined as potent electrochemiluminescent (ECL) materials. The characteristics of these complexes, regarding their electrochemical redox potentials and relative ECL intensities for tripropylamine were
