Abstract: A new non-amphiphilic biferrocene connected by a conjugated bridge group is synthesized and characterized. The biferrocene is able to form a relatively stable monolayer.As it is mixed with arachidic acid, the mixed monolayer is easily assembled to LB film.The UV-Vis spectra show that the aggregate is formed in the molecules on monolayer.By means of scanning electron microscope, the morphological structure of biferrocene and arachidic acid on LBfilm has been observed, and phase separation in the mixed film can be monitored.The electrochemical reaction of Fe(CN)63-/Fe64-(CN)solution is electrocatalyzed by the mixed LB film on ITO electrode. and electrochemical oxidation reaction.of ascorbic acid can be improved by the mixed film.
