Langmuir–Blodgett Films of Ferrocene Sulfide and Sulfone Derivatives with a Long Alkyl Chain

With ferrocenyl octadecyl sulfide, stable monolayers on water surface can be obtained by mixing with stearic acid or by oxidizing to the sulfone derivative and can be easily deposited on solid supports to form well-organized LB films, as confirmed by polarized IR spectra and X-ray diffraction. The LB films exhibit electrochemical activity.
