摘要：

Poly(vinylbenzyl chloride) (PVBC) nanospheres synthesized via emulsion polymerization are used as the substrate for subsequent attachment of viologen moieties. The viologen-functionalized nanospheres can undergo photoinduced reaction with gold ions resulting in the formation of well-dispersed gold nanocrystals with diameters ranging from a few nanometers (see Figure, left) to 15 nm (Figure, right).
