Supramolecular association behavior of a strong C60 receptor with conjugated pentacene and tetrathiafulvalene moieties in solution and in the solid state†
Abstract
A π-extended tetrathiafulvalene (exTTF) containing a conjugated pentacene moiety showed a large binding affinity toward C60 in solution. The crystal structure analysis of the cocrystal formed by this exTTF and C60 revealed that strong π–π interactions existed between C60 and naphthalene and 1,3-dithiol-2-ylidene units.
