Description:
The effects of the non-ionic surfactant Triton X-100 (polyethylene glycol tert-octylphenyl ether) on the properties of Os(phen)"2(dppene)^2^+ (phen=1,10-phenanthroline and dppene=bis(diphenylphosphino)ethene) electrochemiluminescence (ECL) have been investigated. The anodic oxidation of Os(phen)"2(dppene)^2^+ produces ECL in the presence of tri-n-propylamine (TPrA) in aqueous surfactant solution. Increases in ECL efficiency (>=3-fold) and TPrA oxidation current (>=2.0-fold) have been observed in surfactant media with experiments supporting adsorption of surfactant on the electrode surface.
