摘要
应用循环伏安法研究了甲酰基二茂铁、乙酰基二茂铁和1,1′-二乙酰基二茂铁在高氯酸钠的乙醇浴液中和Pt电极上的电化学行为。用循环伏安法理论分析实验结果表明,上述二茂铁衍生物发生了准可逆的电荷转移反应,得出了相应的电荷转移反应传递系数α和电极反应速率常数K_?。讨他了有关取代基对电极过程动力学参数的影响。
The electrochemical behavior of derivatives of ferrocene on platinum electrodewas investigated by cyclic voltammetry measurements in solution of ethanol containingNaClO_4 as supporting electrolyte. It was revealed that the reactions werequasi-reversible. FeX-FeX^+ +e for three different deriratives of ferrocene containing thesubstituent chains-formyl. or-acetyl, or-1, 1'-acetyl group respectively. Theelectrochemical kinetics parameters (α and K_s) are calculated form the resultsobtained. The influences of the substituted groups on the kinetic parameters of electrodeprocesses are discussed for the investigated compounds.
