中文摘要：

在这份报纸，三种水溶性的 fullerene 衍生物分别地经由 electrophilic 增加反应和 cycloaddition 反应被综合。这些衍生物的化学作文描述显示了 C60 的成功的准备(哦) x， C60 (C (COOH ) 2 ) x 和 C60 (哦) x (NHCH2COOH ) y fullerene 衍生物。聚集和形态学描述证明三种衍生物在水里有球形的聚集组织的理想和优秀可分散性，特别 C60 (哦) x 和 C60 (C (COOH ) 2 ) x。衍生物作为润滑剂添加剂扮演了的 fullerene 的润滑油表演在 01 wt% 的范围在不同集中被调查。结果显示 polyhydroxyl 和羧基的衍生物的增加能改进润滑油性质，它导致了减小至多穿到大约 40% 。fullerene 分子的优化替换可能具有他们的分发性质的利益，在水里润滑行为基于润滑油，这被归因。

英文摘要：

In this paper,three kinds of water-soluble fullerene derivatives were synthesized via electrophilic addition reaction and cycloaddition reaction,respectively.The chemical composition characterizations of these derivatives indicated the successful preparation of C60（OH）x,C60（C（COOH）2）x and C60（OH）x（NHCH2COOH）y fullerene derivatives.The aggregation and morphology characterizations showed that the three kinds of derivatives had an ideal spherical aggregating structures and excellent dispersibility in water,especially C60（OH）x and C60（C（COOH）2） x.The lubrication performance of the fullerene derivatives acted as lubricant additives were investigated at different concentrations in the range of 0-1 wt%.The results indicated that the addition of polyhydroxyl and carboxylic derivatives could improve the lubrication properties,which led to the reduction of wear to about 40% at most.It is attributed that the optimized substitutions of fullerene molecules may be of benefit to their distribution properties and lubricating behaviors in water based lubrication.
