The mixed valence state formation in a metallic Langmuir film on the water surface is reported. The mixing molecular system of BEDO-TTF (BO) and stearic acid (SA) forms a bilayer film, where a SA layer is lying on the BO layer, on the water surface. The polarization-modulated IR reflection absorption spectroscopy (PM-IRRAS) reveals a metallic optical property in the BO layer described by Drude model. Hydrogen bonding (R-COOHOOC-R)(-) anions in the SA layer are suggested by the comparison of IR spectrum of carboxylic salt of BEDT-TTF.
