Generation of a series of Bn fused oligo-naphthalenes (n = 1 to 3) from a B1-polycyclic aromatic hydrocarbon.

A series of Bn-PAHs have been prepared by functionalisation of a B1-PAH, leading to the first only boron doped B3-PAH to the best of our knowledge. These Bn-PAHs represent the first three members of a series of {B-Mes} fused oligo-naphthalenes and trends in key properties of this series have been elucidated.
