LANGMUIR-BLODGETT-FILM OF A NEW BIFERROCE NE DERIVATIVE CONNECTED BY A CONJUGATED BRIDGE GROUP AND ITS ELECTROCATALYSIS

A new non-amphiphilic biferrocene connected by a conjugated bridge gro up 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 sho w that the aggregate is formed in the molecules on monolayer, By means of scanning electron microscope, the morphological structure of bifer rocene and arachidic acid on LB film has been observed, and phase sepa ration in the mixed film can be monitored, The electrochemical reactio n of Fe(CN)(6)(3-)/Fe(CN)(6)(4-) solution is electrocatalyzed by the m ixed LB film on ITO electrode, and be improved by the mixed film.
