A helical syndiotactic poly(methyl methacrylate) (st-PMMA) encapsulates C₆₀ molecules within its helical cavity to form a supramolecular peapod-like molecular wire. In their Communication (DOI: 10.1002/anie.201208481), S. Qi, S. Irle, E. Yashima, and co-workers report that sandwich devices fabricated using this helical st-PMMA/C₆₀ inclusion complex exhibit an irreversible electrical switching effect, which results from a violent Coulomb explosion in the peapod C₆₀ wires during the charge injection process
