Abstract

The effects of the nonionic surfactant Trition X-100 (polyethylene glycol tert-octylphenyl ether) on the properties of tris (2-phenylpyridine)iridium(III) Ir(ppy)₃ electrochemiluminescence (ECL) have been investigated. The anodic oxidation of Ir(ppy)₃ produces ECL in presence of tri-n-propylamine (TPrA) in aqueous surfactant solution. Increases in ECL efficiency (_>10-fold) and TPrA ocidation current _>2.0-fold) have been observed in surfactant media. The data supports adsorption of surfactant on the electrode surface, thus facilitating TPrA and Ir(ppy)₃ oxidation and leaning to higher ECL efficiencies.
