Back Cover: Site‐Specific Reduction‐Induced Hydrogenation of a Helical Bilayer Nanographene with K and Rb Metals: Electron Multiaddition and Selective Rb+ Complexation (Angew. Chem. Int. Ed. 10/2022)

Reduction‐induced hydrogenation of a helical bilayer nanographene (C138H120) with K or Rb in 18‐crown‐6 is reported by Israel Fernández, Marina A. Petrukhina, Nazario Martín, and co‐workers in their Research Article (e202115747). DFT calculations predict that localization of the first two electrons in the helicene moiety leads to a site‐specific hydrogenation at the carbon atoms located on the edge of the central [6]helicene backbone (pink hydrogens). The third electron forms a radical trianion on the HBC leading to a final Rb complex. [ABSTRACT FROM AUTHOR]
