The invention relates to novel dinaphtho[2,3-a:2',3'-h]phenazine conmpounds, to methods for their preparation and intermediates used therein, formulations comprising them, the use of these compounds and formulations as semiconductor material in organic electronic (OE) devices, and OE devices comprising these compounds and formulations.
activity of N−C(α)−C(β1) region of the free radical hybrid determine the regioselectivity of polycyclic aromatic amines (PAAs) electrochemical oxidation towards carbazole and phenazine based aza-helicenes. This work would pave the way for precise construction of heteroatom fused helical large π-conjugated system using direct splicing strategy from PAHs derivatives.
