Abstract
AbstractThe [6.6]cyclophanehexaene hydrocarbon 6a and the dimethoxy[6.6]cyclophanehexaene 6b are prepared starting with the unsaturated diacid 1. An X‐ray analysis of 6a exhibits a planar molecular skeleton. NMR and optical data prove a not fully conjugated macrocyclic π system and its division into two largely separate chromophores.
