Boron-nitrogen-doped polycyclic aromatic hydrocarbons (BN-PAHs), as a kind of important functional molecule,have wide applications in the field of organic optoelectronics. Aiming at the fact that the introduction of BN units has the unique effect on the optoelectronic properties of PAHs, but the synthesis methods of BN-PAHs, as well as systematic investigation of the effect of BN units on PAHs’ optoelectronic properties, are still needed. We developed new external-stimuli-driven elimination and electrophilic borylation reactions via investigation of different substrates and reaction conditions, achieved the diverse synthesis of different categories of BN-PAHs, and then investigated the relationship between the locations of BN units and the stability and optoelectronic properties of BN-PAHs experimentally and computationally.

The first earth-abundant cobalt-catalyzed cycloamination of indolylquinones and various(hetero)aromatic amine under ligand-free conditions for the synthesis of polycyclic N-heterocycles has been developed. The process allows facile access to polycyclic N-heterocycles with tolerance of chloride, bromide, amino, thio, etc. groups in moderate to high yields(up to 89%). Inaddition, The photophysical properties of the synthesized products were evaluated. These products exhibit interesting fluorescence properties, which is promising for fluorescent probes.
