中文摘要：

氧化石墨烯表面含有大量的含氧基团,可以与有机显色剂5-氯-4-（2-吡啶偶氮）-1,3-二氨基（5-Cl-PADAB）上位阻小的非活性位点氨基发生偶联,制备得到5-Cl-PADAB功能化石墨烯.采用Hummer法获得氧化石墨烯,对其进行酰氯化处理,与5-Cl-PADAB偶联.产物直接离心分离,得到黑色粉末.采用傅里叶红外光谱、X射线单晶衍射和核磁共振氢谱等方法对产物结构进行分析.

英文摘要：

Large number of oxygen-containing groups of graphene oxide makes it couple with low resistance inactive site amino of organic chromogenic agent 4-[ （5-Chloro-pyridine） azo ]- 1, 3-Diaminobenzene （5-Cl-PADAB） , to obtain 5-Cl-PADAB functionalized of graphene oxide. Graphene oxide was prepared by Hummer method, then treated with Acyl chlorination, and coupled with 5-Cl-PADAB. The product of black powder was gotten by centrifugal separation. Fourier infrared spectrum, X-ray single crystal diffraction and nuclear magnetic resonance hydrogen spectrum were employed to analyze its structure.
