制备了一种二茂铁分子嵌入杂化双层膜（HBM）的电极支撑体系，并对其进行了表征。通过改变HBM的脂质和烷醇结构单元，研究了二茂铁分子的氧化还原性质。嵌入的二茂铁的中点电位和电子转移速率被发现是依赖于电解质的疏水性和在该位置处的二茂铁在HBM相对于电极和溶液的距离。此外，评价了脂质包埋的二茂铁离子氧化溶液相抗坏血酸的能力，发现其取决于抗坏血酸的性质。
An electrode-supported system in which ferrocene molecules are embedded in a hybrid bilayer membrane (HBM) has been prepared and characterized. The redox properties of the ferrocene molecules were studied by varying the lipid and alkanethiol building blocks of the HBM. The midpoint potential and electron transfer rate of the embedded ferrocene were found to be dependent on the hydrophobic nature of the electrolyte and the distance at which the ferrocene was positioned in the HBM relative to the electrode and the solution. Additionally, the ability of the lipid-embedded ferrocenium ions to oxidize solution phase ascorbic acid was evaluated and found to be dependent on the nature of the counterion.
