【摘要】 采用简单的氯胺-T反应制备了碘化的多羟基单壁碳纳米管(SWNTols),发现碘与SWNTols的碳形成共价键.用同步辐射光电子能谱(SRXPS)和光电子能谱(XPS)测量发现,样品的碘的电子结合能与两个具有C-I共价键的参考物——苯的衍生物,完全一致,而与具有离子性质的NaI的结合能不同.这个结果对单壁碳纳米管今后的生物医学应用研究有实际意义.更多还原

【Abstract】 A simple method was used to synthesize the iodinated multi hydroxylated SWNTs (SWNTols) by the reaction of SWNTols with NaI in the presence of strong oxidant N-chloro-p-toluenesulfonamide. The formation of the C-I covalent bond was verified by comparing the electron binding energies of iodine of I-SWNTols and the reference materials, which were measured with the synchrotron radiation X-ray photoemission spectroscopy (SRXPS) as well as the conventional X-ray photoelectron spectroscopy (XPS). This result will be useful in applications of SWNTs in the biomedical and pharmaceutical sciences.更多还原
