Novel
boron-fused double [5]helicenes were synthesized from hexabromobenzene
in two steps via Hart reaction and demethylative cyclization. The
parent helicene shows excellent ambipolar conductivity, which can
be explained by unique 3D π-stacking with a brickwork arrangement.
Moreover, the introduction of four tert-butyl groups
suppresses racemization, enabling optical resolution. The enantiomerically
pure helicene shows deep blue fluorescence with Commission Internationale
de l′Eclairage coordinates of (0.15, 0.08) and circularly polarized
luminescence activity.
