Abstract

original image

A painless way to tighten your belt: Structural characterization of the multiply charged fragment of an armchair nanotube that was formed by reduction of the neutral molecule with potassium metal revealed a remarkable elliptical distortion of the carbon core (see picture). The resulting tetraanions underwent supramolecular aggregation with potassium cations, and solvated guests were encapsulated inside the negatively charged polyarene cavity.
