Synthesis of Functionalizable Boron‐Containing π‐Electron Materials that Incorporate Formally Aromatic Fused Borepin Rings

Abstract

Not a natty BOH: Borepin-based extended π-electron molecules contain bulky substituents that shield the vacant boron p orbitals and allow synthetic manipulation and purification under ambient conditions. These borepin-containing compounds (see picture; Mes*=1,3,5-tris(tert-butyl)phenyl; B orange, C gray) display reversible cathodic electrochemistry and can be viewed as n-type analogues to bent acene hydrocarbons.
