Abstract

The highly enantioselective synthesis 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). Crystal structures and photophysical properties of these helically chiral 1,1′-bitriphenylenes have also been studied.
