Abstract

The geometry imposed by the coordination sphere around the metal, together with the choice of the “arms” can be advantageously used to build corannulene-based molecular tweezers, which show great affinities for C₆₀ and C₇₀, as revealed by NMR titration experiments, mass spectroscopy, DFT calculations and the single crystal X-ray structural analysis of the compound C₆₀ ⊂ 1.
