The spectroscopic and electrochemiluminescence (ECL) properties of Ru(bpy)32+ when in the presence of 2,2,2-Trifluoroethanol (TFE) and the non-ionic surfactants Triton X-100 and Zonyl FSN are reported. The effects of TFE and surfactants were confirmed to increase ECL individually, but the effects were not shown to be additive. TFE is suspected of affecting the adsorption of surfactant to the electrode surface. In a separate project, the spectroscopic and ECL properties of Ir(ppy)3 in the presence of TFE is reported. Photoluminescence spectra of Ir(ppy)3 in a 30% TFE solution showed increased efficiencies over purely aqueous and 50% Acetonitrile (MeCN) solutions. ECL in a 30% TFE solution was increased over a purely aqueous system yet lower than a 50% MeCN solution.
