Isolation and Characterization of the Cycloparaphenylene Radical Cation and Dication

Charged nanobelts: The radical cation and the dication of [8]cycloparaphenylene ([8]CPP) were prepared and isolated as hexahaloantimonate salts by the one‐ or two‐electron chemical oxidation of [8]CPP with NOSbF6 or SbCl5. ESR spectroscopy of CPP.+ and single‐crystal X‐ray analysis of CPP2+ demonstr...

Zusammenfassung:Charged nanobelts: The radical cation and the dication of [8]cycloparaphenylene ([8]CPP) were prepared and isolated as hexahaloantimonate salts by the one‐ or two‐electron chemical oxidation of [8]CPP with NOSbF6 or SbCl5. ESR spectroscopy of CPP.+ and single‐crystal X‐ray analysis of CPP2+ demonstrated that the spin and charge were equally and fully delocalized over the para‐phenylene rings.
