Super-stable, high-quality Fe3O4 dendron-nanocrystals dispersible in both organic and aqueous solutions

by Kim, Myeongseob; Chen, Y. F.; Liu, Yongcheng; Peng, Xiaogang

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).
