Enhanced association for C70 over C60 with a metal complex with corannulene derivate ligands

Dalton Trans. 2014 Nov 14;43(42):15693-6. doi: 10.1039/c4dt02078b.

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.
