Electrogenerated chemiluminescence (ECL) from an organized monomolecular layer of a surfactant derivative of Ru(bpy)/sub 3//sup 2 +/ consisting of a single stearamidomethylene chain linked to one bipyridine unit at the 4-position and abbreviated Ru-(bpy)/sub 2/(bpy-C/sub 19/)/sup 2 +/ has been observed at the surfaces of In-doped tin oxide, Pt, and Au electrodes. The surfactant monolayer was coated on the substrate electrodes by the Langmuir-Blodgett method. ECL was generated in an electrochemical cell containing an aqueous oxalate solution by applying a positive potential to the electrode modified by the monolayer of Ru(bpy)/sub 2/(bpy-C/sub 19/)/sup 2 +/. The ECL of the emitter monolayer deposited on an In-doped SnO/sub 2/ electrode was quite intense with an emission maximum at ca. 680 nm. The ECL of the monolayer deposited on Pt and Au electrodes was generally 10/sup 2/-10/sup 3/ times weaker than that on SnO/sub 2/, but still easily detectable.
