摘要

((5-(3-(acetylthio)propoxy)-1,3-phenylene)bis(methylene))bis((4,4bipyridin)-1-ium) has beensuccessfully synthesized by a straightforward reaction and its electrochemical properties of self- assembled monolayers (SAMs) on Au electrode are measured by cyclic voltammetry (CV) andelectrochemical impedance spectroscopy (EIS). The barrier property of the SAMs-modified surface isevaluated by using potassium ferro/ferri cyanide. The results suggest that its SAMs can reduce thecharge 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 andmorphological 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 wehave ever got.
