To develop an improved synthetic route to [36](1,2,3,4,5,6)cyclophane (CP) 2, a more practical synthetic route to [35](1,2,3,4,5)CP 3 than the original one was developed, which started from [32](1,...

In the crystal structures of [36](1,2,3,4,5,6)cyclophane 1 and the 1:TCNQ (1:1) complex, the cyclophane moiety is observed as the D6h structure because of the disorder of the molecules with C6h symmetry. In contrast, the C6h structure is observed in
