A bottom-up approach toward stable and monodisperse segments of graphenes with a nitrogen-doped zigzag edge is introduced. Exemplified by the so far unprecedented dibenzo-9a-azaphenalene (DBAPhen) as the core unit, a versatile synthetic concept is introduced that leads to nitrogen-doped zigzag nanographenes and graphene nanoribbons.

The orientational distribution of a set of stable nitroxide radicals in aligned liquid crystals 5CB (nematic) and 8CB (smectic A) was studied in detail by numerical simulation of EPR spectra. The order parameters up to the 10th rank were measured. The directions of the principal orientation axes of the radicals were determined. It was shown that the ordering of the probe molecules is controlled...
