Super-Stable, High-Quality Fe3O4 Dendron–Nanocrystals Dispersible in Both Organic and Aqueous Solutions

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).
