Abstract:The rapid and reliable measurement of hydrogen peroxide (H2O2) is imperative for many areas of technology, including pharmaceutical, clinical, food industry and environmental applications. In this work, a novel multifunctional complex, [Ru(bpy)(2)(luminol-bpy))(PF6)(2) (bpy: 2,2'-bipyridine), was designed and synthesized by incorporating a Ru(II) complex with a luminal group. In the presence of horseradish peroxidase (HRP), reaction of [Ru(bpy)(2)(luminol-bpy)(2+) with H2O2 can be monitored by three sensing channels including photoluminescence (PL), chemiluminiscence (CL) and eletrochemiluminiscence (ECL). The quantitative assays for H2O2 in aqueous solutions using [Ru(bpy)(2)(Luminal-bpy)](PF6)(2) as a probe were established with PL, ECL and CL signal output modes, respectively.
