Abstract

High-quality Fe O 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.

摘要

包覆硬脂酸基团的高质量FeO纳米晶体成功转化为包覆树枝状分子的纳米晶体（树枝状分子-纳米晶体）。聚乙二醇低聚物用作树枝状分子配体的主要端基，这使得树枝状分子-纳米晶体在从二氯甲烷到水的广泛溶剂中具有出色的分散性。
