Abstract
Three pairs of planar chiral heteroarenes were synthesized using palladium-catalyzed Buchwald–Hartwig coupling and hypervalent iodine-mediated oxidative cyclization from optically pure 4-amino[2.2]paracyclophane. Among them, an enantiomer of planar chiral azahelicene was found to have circularly polarized luminescence activity that was remarkably stronger than that of planar chiral heteroarenes.Keywords
