| Abstract: | The self-assembly of polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP)/HAuCl4 complexes in solutions is described. A morphological change from spheres to aggregated spheres, and then to vesicles, all of which contain Au precursor within the micellar corona or vesicle shell, can be prepared from an identical diblock copolymer by controlling the solvent selectivity. The possible mechanisms leading to the morphological transitions are also discussed. This may be a simple, facile route for preparation of a desired gold-containing aggregate. |
