Cyclophanes consisting of the anthracene unit and the aromatic component carrying various substituents at the inner or the outer position (anthracenophanes) have been synthesized. Their structures were characterized by the NMR and the X-ray analyses. NH–π interaction between the anthracene ring and the inner amino group on the opposite ring was observed in this cyclophane system. It has been found out that the λmax values of charge-transfer complexes of anthracenophanes with TCNE are closely related to transannular and NH–π interaction.
已经合成了由
