Conformational Analysis of the Supramolecular Complexation of Diaryl-Substituted Tetrathiafulvalene Vinylogues with Fullerenes.

ABSTRACT: Tetrathiafulvalene vinylogues (TTFVs) functionalized with diaryl substituents (aryl = 1-napthyl, 9-anthryl, and 1-pyrenyl) via click chemistry have been previously synthesized and studied as tweezer-type receptors for binding with C₆₀ and C₇₀ fullerenes. In particular, dianthryl-TTFV exhibits unique selectivity for C₇₀ fullerene, giving rise to effective fluorescence turn-on sensing of C₇₀ in the presence of a large excess of C₆₀ fullerene. This observation indicated that dianthryl-TTFV has a preferential binding affinity for C₇₀ over C₆₀ fullerene, but the reason for such selectivity is unclear. Aiming at addressing this issue, we herein investigated the relative conformational stability of diaryl-substituted TTF
