Herein we report the synthesis and photophysical and supramolecular properties of a novel three-dimensional capsule-like hexa-peri-hexabenzocoronene (HBC)-containing carbon nanocage, tripodal-[2]HBC, which is the first synthetic model of capped zigzag [12,0] carbon nanotubes (CNTs). Tripodal-[2]HBC was synthesized by the palladium-catalyzed coupling of triboryl hexabenzocoronene and L-shaped cyclohexane units, followed by nickel-mediated C?Br/C?Br coupling and subsequent aromatization of the cyclohexane moieties. The physical properties of tripodal-[2]HBC and its supramolecular host–guest interaction with C70 were further studied by UV/Vis and fluorescence spectroscopy. Theoretical calculations revealed that the strain energy of tripodal-[2]HBC was as high as 55.2 kcal mol?1.

Direct C-H borylation of hexa-peri-hexabenzocoronenes (HBCs) has been achieved under iridium catalysis, which allows efficient synthesis of hydroxy-substituted HBCs by oxidation of the boryl groups. Further oxidation of dihydroxy HBC with phenyliodine bis(trifluoroacetate) (PIFA) afforded tetraoxo-substituted HBC without any regioisomers, which can be considered as a π-extended quinone.
