A Silicon-Doped Nanographenic Bowl for Supramolecular Assembly with Fullerenes
A silicon-doped nanographenic bowl, trisilasupersumanene <b>1</b>, was synthesized via a 3-fold palladium-catalyzed sila-annulation from the hexachlorinated trifluorenocoronene. Incorporating silole rings into the aromatic framework leads to new reduction waves in cyclic voltammetry and low-lying LUMO levels. The bowl <b>1</b> exhibits high binding affinity to fullerenes C<sub>60</sub> and C<sub>70</sub>, forming supramolecular complexes <b>1⊃C</b><sub><b>60</b></sub> and <b>(1)</b><sub><b>2</b></sub><b>⊃C</b><sub><b>70</b></sub> with unique packing arrangements. Notably, <b>(1)</b><sub><b>2</b></sub><b>⊃C</b><sub><b>70</b></sub> features a rare clam-like structure in the crystal, entirely different from its binding behavior in solution.
