A Giant Conjugated Molecular Ring


  • We are grateful to Prof. Dr. Hilbert von Löhneysen for suggesting the synthesis of molecular nanocycles for persistent-current experiments, and Dr. Detlef Beckmann and Dr. Heiko B. Weber for their patience in introducing us to some principles of mesoscopic physics. Financial support from the Strategiefond of the Helmholtz Foundation is gratefully acknowledged.

Ever increasing circles? The giant cycle 1 has a diameter of 12 nm making it the largest, shape persistent and monodisperse cyclic molecular structure designed and synthesized to date. A modular approach consisting of a series of subsequent dimerization steps made 1 accessible.
