Abstrak

1, 1”-((5-(3-(acetylthio)propoxy)-1, 3-phenylene)bis(methylene))bis((4, 4’-bipyridin)-1-ium) has been successfully synthesized by a straightforward reaction and its electrochemical properties of self-assembled monolayers (SAMs) on Au electrode are measured by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The barrier property of the SAMs-modified surface is evaluated by using potassium ferro/ferri cyanide. The results suggest that its SAMs can reduce the charge transfer resistance (Rct) and accelerate the electron transfer rate. CV results showed that SAMs-modified Au electrode rapidly recognized Ag+ and had excellent cycle stability. The structural and morphological information has also been obtained by field emission scanning electron microscope (FE-SEM), the Ag composition of SAMs was 15.53% which is much higher than other compounds we have ever got.
