Abstract A detailed Polarization Modulation Infrared Reflection Absorption Spectroscopy (PM-IRRAS), X-Ray Photoelectron Spectroscopy (XPS) and electrochemical study of the interaction of copper(II) aqueous solutions with self-assembled monolayers of carboxylic acid and alcohol functionalized thiols of different lengths on gold is reported. Results show that all of these SAMs retain similar amounts of copper, that the interaction takes place mostly with the terminal functional groups, and that for short chain thiols, the copper is electrically connected to the electrode. Furthermore, upon interaction with the copper solution, most of the carboxylic acid moieties deprotonate, forming a complex with the copper cation. This information is relevant for the intelligent design of surfaces with affinity to metal cations that can be used as electrochemical sensors, or in systems for cleaning contaminated water.

Cu(II) 水溶液与羧酸和醇终止自组装单层的相互作用：表面和界面表征。

摘要 详细的偏振调制红外反射吸收光谱 (PM-IRRAS)、X 射线光电子光谱 (XPS) 和电化学研究铜 (II) 水溶液与不同的羧酸和醇官能化硫醇的自组装单层的相互作用。报告了黄金的长度。结果表明，所有这些 SAM 都保留了相似量的铜，相互作用主要发生在末端官能团，对于短链硫醇，铜与电极电连接。此外，在与铜溶液相互作用时，大部分羧酸部分去质子化，与铜阳离子形成络合物。
