Functionalized graphene oxide (GO-BPh2), was obtained via one step reaction between triphenyl boron and oxygen-containing groups on graphene sheets. In addition, functionalized graphene oxide (GO-Carbene) was obtained via bingel cyclopropanation reaction of active double bands on graphene sheets. Both functionalized materials can be homogeneously distributed into ortho-dichlorobenene. They were characterized by FTIR spectroscopy, UV Vis NIR spectroscopy, thermal gravimetric analysis, raman spectra, and X-ray photoelectron spectroscopy (XPS). FTIR, TGA and XPS results prove that phenyl boron has been successfully attached to the graphene sheets by covalent bonds. And the Raman spectra and XPS confirm that many carbon double bands changed into carbon single bands on graphene sheets after cyclopropanation reaction.
功能化氧化石墨烯（GO-BPh2）是通过三苯基硼与石墨烯片上含氧基团之间的一步反应获得的。此外，功能化氧化石墨烯（GO-卡宾）是通过石墨烯片上活性双键的宾格尔环丙烷化反应获得的。两种功能化材料都可以均匀地分散在邻二氯苯中。它们通过傅里叶变换红外光谱（FTIR）、紫外可见近红外光谱、热重分析、拉曼光谱和X射线光电子能谱（XPS）进行了表征。FTIR、热重分析（TGA）和XPS结果证明苯基硼已通过共价键成功连接到石墨烯片上。拉曼光谱和XPS证实环丙烷化反应后石墨烯片上许多碳双键变成了碳单键。
