C 60 ‐encapsulated species, [C 60 ⊂( 1 ) 2 ]⋅8 toluene and [C 60 ⊂( 2 ) 2 ], are obtained exclusively when p ‐benzylcalix[5]arene ( 1 ) or p ‐benzylhexahomooxacalix[3]arene ( 2 ) react with C 60 or fullerite in toluene. The C 5 or C 3 symmetry axis, respectively, of each calixarene is aligned with the same symmetry element of C 60 and highlights the importance of symmetry matching in the design of host molecules for fullerenes.
