Herein we report synthesis of series of novel both aza- and diaza-helicenes, and phenacenes, which were prepared mainly by photocyclization of corresponding imine precursors. Reaction conditions of photocyclization (i.e. solvent, photocatalyst, type of irradiation, use of water scavenger) were optimized and enhanced. Usage of TEMPO as oxidizing agent leads to improvement of yields up to 72 %. Prepared 2-pyridyl substituted azaphenacenes will be utilized for preparation of potential semiconductive layers in cooperation with IMC of the CAS.
