An easy and environmentally friendly chemical method for the simultaneous reduction and noncovalent functionalization of graphene oxide (GO) using dopamine derivatives is described. The reaction takes place at room temperature under ultrasonication of an aqueous suspension of GO and a dopamine derivative. X-ray photoelectron spectroscopy, FT-IR spectroscopy, and cyclic voltammetry characterizations revealed that the resulting material consists of graphene functionalized with the dopamine derivative. This one-step protocol is applied for simultaneous reduction and functionalization of graphene oxide with a dopamine derivative bearing an azide function. The chemical reactivity of the azide function was demonstrated by a postfunctionalization with ethynylferrocene using the Cu(I) catalyzed 1,3-dipolar cyloaddition.
采用多巴胺衍生物对氧化石墨烯（GO）进行同时还原和非共价功能化的简便、环保的化学方法。该反应在超声作用下于 GO 和多巴胺衍生物的水溶液中于室温下进行。X 射线光电子能谱、傅里叶变换红外光谱和循环伏安法表征表明，所得材料由多巴胺衍生物功能化的石墨烯组成。该一步法可用于同时还原和功能化带有叠氮功能的氧化石墨烯的多巴胺衍生物。通过使用 Cu（I）催化的 1,3-偶极环加成反应，用乙炔基二茂铁进行后功能化，证明了叠氮基的化学反应活性。
