Boron-doped double [6]carbohelicenes: a combination of helicene and boron-doped π-systems.

ABSTRACT: Helicenes, featuring unique helical structures, have a long history as three-dimensional polycyclic aromatic hydrocarbons (PAHs). Incorporation of heteroatoms into helicenes may alter their electronic structures and achieve unexpected physical properties. Here, we disclose fusion of boron-doped π-systems onto helicenes as an efficient strategy to design boron-doped carbohelicenes. Two boron-doped double [6]carbohelicenes were synthesized, which possess the C₅₈B₂ and C₈₆B₂ polycyclic π-skeletons containing two [6]helicene subunits, respectively. The C₈₆B₂ molecule thus represents the largest-size helicene-based boron-doped PAH. A thorough investigation reveals that the helicene moieties and boron atoms endow the polycyclic π-
