Abstract : Electropolymerized films of Ru(v-bpy)3+2 on a tungsten/carbon layered synthetic microstructure (LSM) with a 30A d-spacing exhibit molecular ordering as measured by the x-ray standing wave technique where the reflectivity across the first order Bragg reflection as well as the intensity of the characteristic Ruka fluorescence at 19.3 keV ar simultaneously monitored. A well developed modulation in the Ruka fluorescence intensity is indicative of a molecularly ordered layer. Keywords: electropolymerization, X ray standing waves, synchrotron radiation, Ruthenium compounds.
