Iridium complexes with a chiral metal center and chiral carbons, Λ/Δ-(dfppy)Ir(chty-R) and Λ/Δ-(dfppy)Ir(chty-S), were synthesized and characterized. These isomers have the same steady-state photophysical properties, and obvious offsets in ECD spectra highlight both the chiral sources. Each enantiomeric couple shows mirror-image CPL bands with a dissymmetry factor in the order of 10.
