Synthesis of Boron-Doped Polycyclic Aromatic Hydrocarbons by Tandem Intramolecular Electrophilic Arene Borylation

This is the authors' abstract. We don't add key points for this paper.

Tandem intramolecular electrophilic arene borylation was developed to facilitate access to B-doped polycyclic aromatic hydrocarbons (PAHs). DFT calculations revealed that electrophilic arene borylation occurred via a four-membered ring transition state, in which C-B and H-Br bonds formed in a concerted manner. An organic light-emitting diode employing the B-doped PAH as an emitter and a B-doped PAH-based field-effect transistor were successfully fabricated, demonstrating the potential of B-doped PAHs in materials science.
