通过扫描电化学显微镜（SECM）研究了尖端电极上3-巯基丙酸（MPA）和二茂铁甲醇（FcCH 2 OH）之间的分子间氢键。借助MPA自组装单分子层（SAM）末端羧基（-COOH）的解离平衡，设计了分子间氢键的可逆组装和分解。基于该设计，实现了分子间氢键的pH调节组装和分解。使用明确的 SAM 作为模型膜提供了一种简单而实用的方法来探索细胞膜表面的分子识别。
The intermolecular hydrogen bonding between 3-mercaptopropionic acid (MPA) and ferrocenylmethanol (FcCH 2 OH) on the tip electrode was studied by scanning electrochemical microscopy (SECM). The reversible assembly and disassembly of the intermolecular hydrogen bonding were designed with the aid of the dissociation equilibrium of the terminal carboxyl groups (-COOH) of the MPA self-assembled monolayer (SAM). Based on this design, the pH-modulated assembly and disassembly of intermolecular hydrogen bonding have been implemented. The use of well-defined SAM as model membrane provides a simple yet practicable approach to explore the molecular recognition at the cell membrane surfaces.
