成功地将高质量的硬脂酸盐包覆的Fe3O4纳米晶转化为树枝状包覆纳米晶(树枝状纳米晶)。聚乙二醇作为树枝状配体的主要末端基团，提供树枝状纳米晶体优异的分散性；在从二氯甲烷到水的广泛溶剂中(见图)。
High-quality Fe3O4 nanocrystals coated with stearate groups are successfully converted to dendron-coated nanocrystals (dendron-nanocrystals). Poly(ethylene glycol) oligomers are used as major terminal groups for the dendron ligands, which afford excellent dispersibility of the dendron-nanocrystals; in a broad spectrum of solvents, ranging from dichloromethane to water (see Figure).
