11Cycloparaphenylene incorporating a redox-active dithiafulvene moiety provides access to a carbon nanohoop with an unpaired electron along the core

Key Points

• The research aims to investigate the properties of an [11]CPP modified by a dithiafulvalene moiety.
• Synthesis of [11]CPP incorporating a dithiafulvalene moiety
• Characterization of the material in neutral and radical cationic forms
• Analysis of absorption spectra to assess optical properties
• The addition of the dithiafulvalene moiety causes a redshift in the absorption spectrum
• Identification of the material's reversible electron donation characteristics
• Demonstration of the existence of unpaired electrons in the radical cationic form.
