Abstract

As a circular path for electrons a giant macrocycle with a periphery consisting of exclusively conjugation-active units has been designed. With a diameter of 12 nm it is probably the largest synthesized, shape-persistent, and monodisperse cyclic structure to date. In addition, the front wheel of a bicycle is shown, the 16-fold symmetry of which inspired the design of the molecule. For more information on this molecule see the Communication by M. Mayor and C. Didschies on page 3176 ff.
