abstract = {A pair of enantiopure [6]-azairidahelicenes
incorporating chirality at the metal center and on the
helicenic ligand were synthesized by dynamic kinetic
resolution (dkr) of a configurationally labile [4]-helicenic
ligand (4-(2-pyridyl)-benzo[g]phenanthrene, L1H)
using bis-cyclometalated chiral-at-metal only iridium-
(III) precursors as chiral inductors. The origin of the
observed dkr is attributed to the different conformation
and stability of diastereomeric reaction intermediates
formed during the cyclometalation process. The isolated
enantiomers exhibited circularly polarized phosphorescence
(CPP), with j gphos j values of 1.8×10-3},
