| Abstract: | Gold nanoparticles with average diameter of 1.0 nm and narrow size distribution can be easily obtained by disproportionation of Au(+) ions, in the presence of a persulfurated coronene dendrimer that favors encounters between Au(+) ions and protects the resulting small nanoparticles from further aggregation. |
