Non-planar nanographenes are materials with promising prospects for chiroptical and optoelectronic applications. Now bilayer molecular nanographenes composed of two hexa-peri-haxabenzocoronene units linked by a spirocycle have been synthesized. Modulation of the electronic properties of one of the benzocoronene units enables an electron-transfer process between the donor and acceptor moieties, leading to the formation of zwitterionic open-shell bilayer spironanographenes.
