摘要

利用氨基酸修饰的金单晶电极研究了对映体选择性相互作用对手性分子氧化还原反应的影响。R(+)- 或 S(-)-N, N-二甲基-1-二茂铁乙胺在用 L- 或 D-高半胱氨酸（L-/D-Hcy）修饰的 Au(111) 上的氧化还原峰值电流密度取决于这些手性的组合。Hcy/Au(100) 与氧化还原峰值电流密度无关。Au(111) 和 Au(100) 之间 Hcy 分子排列的差异极大地影响了电极界面上的对映选择性氧化还原反应。

Dependence on the Crystallographic Orientation of Au Single Crystal Surfaces modified with Homocysteine toward Enantioselective Redox Reactions

Effects of enantioselective interactions on redox reactions of chiral molecules were studied using Au single crystal electrodes modified with amino acids. The redox peak current densities of R(+)- or S(–)-N, N-dimethyl-1-ferrocenylethylamine on Au(111) modified with L- or D-homocysteine (L-/D-Hcy) depended on the combination of these chiralities. Hcy/Au(100) showed no dependence on redox peak current densities. The difference in the molecular arrangement of Hcy between Au(111) and Au(100) greatly affects enantioselective redox reactions at the electrode interface.
