Two disulphide-bond linked diferrocenylarylamines, p-( Fc-Ph-NH-CH2-Ph-S ) 2 and m-( Fc-Ph-NH-CH2-Ph-S ) 2 , were prepared by reducing C-N double bond and deprotecting acetylthio group of two Schiff bases with sodium borohydride simultaneous-ly. These Schiff bases were synthesized by reacting p or m-ferrocenyphenylamines with p-acetylthiobenzaldehyde. Nano-Au/glassy carbon electrode,electrochemically deposited gold nanocrystals on glassy carbon electrodes, was modified by two disulphide-bond linked diferrocenylarylamines through self-assembly technique. The electrochemical behaviors of the modified nano-Au/glassy car-bon electrodes were explored in detail with cyclic voltammetry and electrochemical impedance spectroscope. These modified Au/glassy carbon electrodes exhibited a pair of reversible redox peaks in LiClO4-CH3 CN solution and showed electrocatalytic activity for oxidation of Rutin.
