We observe a very distinct electrogenerated chemiluminescence (ECL) behavior of Ru(bpy)(3)(2+) at screen printed carbon electrode (SPCE) preanodized under different electrolytes. Considering the fact that different oxo-surface groups can be formed under different preanodization conditions, the role of oxygen functionalities to the ECL behavior at the preanodized SPCE was studied. It is concluded that the much enhanced ECL of Ru(bpy)(3)(2+) was attributed from the alcoholic hydroxyl group on the preanodized SPCE surface. (C) 2011 Elsevier B.V. All rights reserved.
