摘要：

(Chemical Equation Presented) Polymer brushes are grown on both hydrophobic and hydrophilic nanocrystals by surface-initiated atom-transfer radical polymerization. The poly{[2-(dimethylamino)ethyl] methacrylate}-coated nanocrystals are well dispersed in both water and most organic solvents without detectable aggregation and deterioration of their intrinsic properties. This methodology paves a simple and efficient way to direct nanocrystals into specific media. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
