| Abstract: | Supra‐mega ion pairing : Multicationic organoruthenium dendrimers show a notable tendency to self‐aggregate when the concentration is increased, leading to megamers. This tendency increases with the generation. The self‐aggregation of dendrimers to megamers is coupled with a decrease in the extent of ion pairing, as illustrated.  |
