New gold nanoparticles covered with cyclic phenylazomethine (CPA) were obtained by a one-pot synthesis. It is confirmed by XPS that imines of CPA in the nanoparticles (Au-CPA) are partially reduced to amines. The amine part of CPA in Au-CPA is attached to the surfaces of gold nanoparticles, and the imine part works as a redox-active site. A glassy carbon electrode modified with Au-CPA was revealed to work as an electrochemical probe for metal ion sensing.
通过一锅合成法得到了一种新的、表面覆盖有环状苯亚甲胺（CPA）的金纳米粒子。XPS 证实纳米粒子中的 CPA 亚胺（Au-CPA）部分被还原成了胺。Au-CPA 中的 CPA 胺部分附着在金纳米粒子的表面，而亚胺部分则作为氧化还原活性位点。研究表明，用 Au-CPA 修饰的玻碳电极可用作金属离子传感的电化学探针。
