Tribenzotriquinacenes Bearing Six-Fold Benzofuran Extensions: Electron-Rich C3v-Symmetrical Hosts for C60

New tribenzotriquinacene (TBTQ) hosts bearing six-fold peripheral benzofuran functionalization have been synthesized. The three polycondensed arene wings were shown to operate optically independently and to generate deeply bowl-shaped C-3v-symmetrical frameworks that act as relatively weak hosts toward C-60, as revealed by H-1 NMR spectroscopy.
