Frontispiece: Concise Synthesis and Facile Nanotube Assembly of a Symmetrically Multifunctionalized Cycloparaphenylene

Cycloparaphenylene Organic molecules with a cyclic π‐conjugation, such as cycloparaphenylene (CPP), have attracted much attention because of their fascinating structures, unique properties, and potential applications in materials science. In their Communication on page 18900 ff. , K. Tanaka and co‐workers report the concise synthesis of C 3 ‐symmetrical [12]CPP‐hexacarboxylate by a rhodium‐catalyzed macrocyclization. Further, a structurally uniform nanotube assembly was achieved in the crystalline state through multiple hydrogen‐bonding interactions between C 3 ‐symmetrical functionalization of CPP and highly polar alkoxycarbonyl groups.
