Inside Cover: Dianion and Dication of Tetracyclopentatetraphenylene as Decoupled Annulene‐within‐an‐Annulene Models (Angew. Chem. Int. Ed. 6/2022)

Abstract

Dianion and dication of a tetracyclopentatetraphenylene derivative were generated and characterized by spectroscopic methods and X-ray crystallography to reveal that the outer and inner conjugation circuits are significantly decoupled as theoretically predicted. The magnetically induced ring currents of the outer and inner circuits flow clockwise and counterclockwise, respectively, in the same direction as the trains run on the outer and inner loops of Osaka Loop Line, as reported by Ichiro Hisaki, Marina A. Petrukhina, Tohru Nishinaga, Masayoshi Nakano, Yoshito Tobe, and co-workers in their Research Article (e202115316).
