Zusammenfassung:[2.2] Paracyclophane quinhydrones with intercalated benzene rings have now been synthesized for the first time in the form of their methyl ethers (1) and (2). Their broad CT band must be due to an intramolecular CT transition; the charge is transmitted in “vertical conjugation” through the π‐electron system of the benzene. Orientation dependence of the CT absorption as observed in simple donor‐acceptor 2.2 paracyclophanes is almost completely absent.
