在玻碳电极上, 联吡啶钌[Ru(bpy)32＋]于＋1.50 V (vs. Ag/AgCl)左右被氧化为Ru(bpy)33＋, 该氧化态离子与碱性水溶液中(pH 8.2)的OH•反应生成激发态的[Ru(bpy)32＋*]而发光. 研究比较了15种金属离子对Ru(bpy)32＋碱性水溶液电致化学发光的影响, 并对这些影响进行了初步的解释.

关键词: 电致化学发光, 联吡啶钌, 金属离子

Tris(2,2'-bipyridine) ruthenium(II) [Ru(bpy)32＋] was oxidized to its oxidated state, Ru(bpy)33＋, on a glassy carbon electrode at the potential of ＋1.50 V (vs. Ag/AgCl). Electrochemiluminescence (ECL) was caused by the reaction between Ru(bpy)32＋ and hydroxyl radical, OH•, generating the excited state of Ru(bpy)32＋*. The effects of 15 kinds of metal ions on the Ru(bpy)32＋ ECL were studied.

Key words: electrochemiluminescence, tris(2,2'-bipyridine) ruthenium(II), metal ion
