中文摘要：

本实验制备羧基化纳米金,以氯化亚砜进行酰胺化处理,再与4-[（5-氯-吡啶）偶氮]-1,3-二氨基苯（5-Cl-PADAB）耦合,得到5-Cl-PADAB功能化纳米金团簇。通过紫外分光光度计,红外以及XRD分别表征其结构和性能。结果表明：功能化前的曲线和功能化后的曲线在形状上发生了很大不同,最大吸收波长也向长波方向发生移动（红移）。

英文摘要：

A In this paper, amination nano gold was prepared, then amidated with sulfoxide chloride to couple with 4 - [（5-chloro-pyridine） azo]-1, 3- diaminobenzene （5-Cl-PADAB） forming get 5-Cl-PADAB functionalized nano gold clusters. Ultraviolet spectrophotometer, IR and XRD were employed to character the structure and performance respectively. The results indicated that 5-ClPADAB functionalized nano gold clusters showed different shape, the maximum absorption wavelength move to longer wavelength （red shift）.
