Abstract

It was found that stannous chloride (SnCl2), as a popular inorganic reducing reagent, could obviously enhance the electrochemiluminescence (ECL) of tris(2,2′-bipyridyl) ruthenium(II) (Ru(bpy)32+) in aqueous solution. Some factors affecting the ECL reactions between Ru(bpy)32+ and Sn2+, including pH, concentrations of coreactant, and electrode materials, were investigated by comparison with a classic ECL coreactant tripropylamine (TPA). The Ru(bpy)32+–Sn2+ ECL coreactant system produces stronger and more stable ECL signals, can keep its excellent ECL activity over a wider pH range and has more choices in using electrode materials than the Ru(bpy)32+–TPA ECL coreactant system. The ECL mechanism of the Ru(bpy)32+–Sn2+ coreactant system was also studied in detail.
