6,7-Bismethoxy-2,11-dihydroxytetraphenylene (1), a novel building block of tetraphenylene-derived macrocycles, was synthesized via palladium-catalyzed cross-coupling reactions and characterized by X-ray diffraction. The relevant macrocyclic hosts derived from 1 have well-defined structures with fixed conformations both in solution and solid state. They showed efficient and unique properties toward complexation with fullerenes C60 and C70 in toluene.
Keywords: fullerenes; host-guest chemistry; macrocycles; synthesis; tetraphenylene.
