摘要
合成了一种水溶性富勒烯衍生物——富勒烯乙二胺,分别采用60 Co源和中子加速器等辐照装置,并结合红外光谱(FTIR)、电子自旋共振技术(ESR)和电喷雾质谱(ESI-MS)等表征手段,比较考察了富勒烯乙二胺与香兰素对受γ射线和中子等高能射线或粒子照射所产生自由基的清除性能。结果表明:对于经γ射线和中子辐照产生的自由基,所制得的富勒烯乙二胺均表现出了较好的抗辐射损伤特性;相同条件下对样品辐照所产生的自由基的清除性能明显优于市购的香兰素。
In this paper,a water-soluble fullerene derivatives has been synthesized.The products have been characterized by the FTIR,ESR and ESI-MS.The free radical elimina-tion capabilities of the fullerene derivatives and vanilin have been investigated throughγand neutron irradiation.The results show the fullerene derivatives indicate better anti-radiation damage performance under the same conditions,and the free radical elimination capability of the fullerene derivatives is better than vanilin.
