Dish it up : The first bowl‐shaped o ‐semiquinone radical with a sodium cation (see picture) has been synthesized, and its 3D spin‐ and charge‐delocalized nature and redox properties have been evaluated. The concave–convex dynamic behavior of the ion pair was also investigated in a quantitative manner using ESR and ENDOR/TRIPLE measurements and sophisticated DFT calculations.
