A simple synthetic route was developed to prepare hard-to-prepare polycyclic (hetero)aromatic compounds with the [1,2,5]chalcogenodiazolo[3,4-b]pyrazine scaffold based on intramolecular nucleophilic aromatic hydrogen substitution reaction. The synthesized polycyclic systems were demonstrated to be narrow-bandgap (from 1.25 to 1.44 eV) n-type organic semiconductors through electrochemical and photophysical measurements, with energy levels comparable to commercially available electronic semiconductors.

Electrochemical and photophysical measurements demonstrated that the synthesized polycyclic systems can be considered as narrow-bandgap (from 1.25 to 1.44 eV) n-type organic semiconductors, the energy levels of which are comparable to those of commercially available electronic semiconductors.
