a Previous reported BO-PAHs. b Design concept of versatile skeletal editing and facile synthesis of dBO-PAHs through one-pot strategy developed in this work. The versatile skeletal editing can be easily realized by Ar1, Ar2 or OMe position regulation; the arrows indicate the position of electrophilic borylation directed by the OMe group. Ph, phenyl group, Mes, 2,4,6-trimethylphenyl group, Ar1, Ar2, aryl group, R, R1, R2, substituent group.
