Near-infrared electrochemiluminescence from Au-25(SC2H4Ph)(18)(+) clusters co-reacted with tri-n-propylamine

The oxidation of Au-25(SC2H4Ph)(18) +C6F5CO2- clusters along with tri-n-propylamine (TPrA) as a co-reactant produces very strong near-infrared electrochemiluminescence with emission peak wavelengths (872 and 945 nm) and intensities depending on the TPrA concentration and working electrode potential.
