以C60和精氨酸为原料经亲核加成反应合成得到C60精氨酸,C60精氨酸再与硝酸铅反应得一种C60金属盐衍生物—C60精氨酸铅盐。同时采用傅里叶变换红外光谱(FTIR)、质谱(MS)、紫外可见光谱(UV-Vis)、原子吸收(AAS)、X射线衍射(XRD)、X射线光电子能谱(XPS)以及元素分析等测试手段对产物结构进行了表征。采用热重分析法对其失重情况进行了研究,失重率为57.86%,采用差热分析法对C60精氨酸铅盐的热稳定性进行了研究,结果表明,在空气气氛下,DSC分解峰值温度为285、435℃;目标产物表现出良好的热稳定性。
The C60 arginine was synthesized by nucleophilic addition reaction of C60 and arginine. C60 arginine was reacted with lead nitrate to obtain a C60 metal salt derivative-C60 arginine lead salt. At the same time, FTIR, MS, UV-Vis, AAS, XRD, XPS and elemental analysis The test methods such as product structure were characterized. Thermal gravimetric analysis was used to investigate its weightlessness. The weight loss rate was 57.86%. The thermal stability of C60 arginine lead salt was studied by differential thermal analysis. The results showed that under air atmosphere, the peak value of DSC decomposition The temperature was 285,435 ° C; the target product showed good thermal stability.
