The highly enantioselectivesynthesis of helically chiral 1,1'-bitriphenylenes has been achieved via rhodium-catalyzed double [2 + 2 + 2] cycloaddition of biaryl-linked tetraynes with 1,4-diynes (up to 93% ee). Crystalstructures and photophysicalproperties of these helically chiral 1,1'-bitriphenylenes have also been studied.
