Study of the electrochemiluminescence based on the reaction of hydroxyl compounds with ruthenium complex

The electrochemiluminescence (ECL) phenomena of some hydroxyl compounds in the presence of tris(2,2'-bipyridyl) ruthenium(III)[Ru(bpy)(3)(2+)] have been found. The experiments were performed in a flow injection system equipped with a thin-layer electrolysis cell. A three-electrode system with a working electrode of a glassy carbon disk (22.1 mm(2)), was used for potentiosatic control of the electrolytic system. The ECL behaviors of sucrose, fructose, glucose, mannose, glycerol, ascorbic acid, citric acid, tartaric acid, some monohydric alcohols and polyhydric alcohols, have been discussed. The ECL reaction mechanisms of these compounds and Ru(bpy)(3)(2+) were also discussed.
