Enantiopure [6]-azairidahelicenes, combining chirality at the metal center and at the helicenic fragment, are readily accessible by an effective dynamic kinetic resolution (dkr) of a configurationally labile [4]-helicenic ligand. The two isolated enantiomers exhibit perfect mirrored electronic circular dichroism (ECD) and circularly polarized phosphorescence (CPP) signals.
