Whereas treatment of 1,4-hexamethylene-bridged benzene [6]paracyclophane (1) with a catalytic amount of H2SO4 gave, as a minor product, dimer 6, along with isomers 4 and 5, similar treatment of 1,4-hexamethylene-bridged naphthalene [6](1,4)naphthalenophane (2) afforded predominantly dimers 7 and 8, together with trimers 9 and 10. The 1,4-hexamethylene-bridged anthracene [6](1,4)thracenophane (3) yielded only trimers 13 and 14.
